Compounds can be very complex combinations of atoms, but many important compounds are fairly simple. Table salt, as we have seen, consists of only two elements: sodium and chlorine. Nevertheless, the compound has properties completely different from either elemental sodium a chemically reactive metal or elemental chlorine a poisonous, green gas. We will see additional examples of such differences in section 3.

- Ionic Bond Test
Chemical bonds are formed when electrons in different atoms interact with each other to make an arrangement that is more stable than when the atoms are apart. What causes atoms to make a chemical bond with other atoms, rather than remaining as individual atoms? A clue comes by considering the noble gas elements, the rightmost column of the periodic table. These elements—helium, neon, argon, krypton, xenon, and radon—do not form compounds very easily, which suggests that they are especially stable as lone atoms. What else do the noble gas elements have in common? Except for helium, they all have eight valence electrons. Chemists have concluded that atoms are especially stable if they have eight electrons in their outermost shell. This useful rule of thumb is called the octet rule, and it is a key to understanding why compounds form. There are two ways for an atom that does not have an octet of valence electrons to obtain an octet in its outer shell. One way is the transfer of electrons between two atoms until both atoms have octets.

- Ionic Bonds Quiz: Trivia Test!
Because some atoms will lose electrons and some atoms will gain electrons, there is no overall change in the number of electrons, but with the transfer of electrons the individual atoms acquire a nonzero electric charge. Those that lose electrons become positively charged, and those that gain electrons become negatively charged. Charged atoms are called ions. Because opposite charges attract while like charges repel , these oppositely charged ions attract each other, forming ionic bonds.

- AQA Chemistry - Ionic Bonding Questions And Answers (Bronze, Silver, Gold) | Teaching Resources
The resulting compounds are called ionic compounds. The second way for an atom to obtain an octet of electrons is by sharing electrons with another atom. These shared electrons simultaneously occupy the outermost shell of both atoms. The bond made by electron sharing is called a covalent bond. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is an octet in the next lower shell.

Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds. Some atoms have nearly eight electrons in their valence shell and can readily gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions. Most nonmetals become anions when they make ionic compounds. Electron Transfer We can use valence electrons and the octet rule to illustrate the electron transfer process between sodium atoms and chlorine atoms.

- Unit 5- Ionic Bonding Test
As demonstrated in Example 1 below , sodium is likely to achieve an octet in its outermost shell by losing its one valence electron. The outermost shell of the sodium ion is the second electron shell, which has eight electrons in it. The octet rule has been satisfied. Figure 3. Fig 3. The Formation of a Sodium Ion. On the left, a sodium atom has 11 electrons. Note that the sodium ion now has an outer electron shell that has eight electrons, fulfilling the octet rule.

In table salt, NaCl, this electron comes from the sodium atom. The Formation of a Chloride Ion. On the left, a chlorine atom has 17 electrons. On the right, the chloride ion has gained an extra electron for a total of 18 electrons and a 1— charge. Note that the chloride ion has now filled its outer shell and contains eight electrons, satisfying the octet rule. In this case, the ion has the same outermost shell as the original atom, but now that shell has eight electrons in it. Once again, the octet rule has been satisfied. With two oppositely charged ions, there is an electrostatic attraction between them because opposite charges attract. The resulting combination is the ionic compound sodium chloride. Notice that there are no leftover electrons. The number of electrons lost by the sodium atom one equals the number of electrons gained by the chlorine atom one , so the compound is electrically neutral.

In macroscopic samples of sodium chloride, there are billions and billions of sodium and chloride ions, although there is always the same number of cations and anions. In many cases, elements that belong to the same group vertical column on the periodic table form ions with the same charge, because they have the same number of valence electrons. Thus, the periodic table becomes a tool for remembering the charges on many ions. Note the convention of first writing the number and then the sign on a multiply-charged ion. Predicting Ionic Charge. The Octet Rule can be used to help you predict how many electrons an element must gain or lose to achieve an electron configuration similar to the Noble Gases.

Note that the first 3 Main Group Columns typically lose electrons to achieve the octet, while columns typically gain electrons to reach the octet. Notice column 4, it is right in the middle and is left blank. Elements in column 4 contain 4 electrons in their valence shell. Thus, they would either need to gain 4 e- or lose 4- to reach the octet state. However, a 4 e- gain or loss is too much charge for one atom to easily hold and typically becomes unstable, unless the atom is very large! Lead for example can lose 4 e-. For most elements in row 4, they tend to share electrons in covalent bonds described in section 4 , rather than gaining or losing electrons to form ionic bonds. First, they show only valence electrons. Second, instead of having a circle around the chemical symbol to represent the electron shell, they have up to eight dots around the symbol; each dot represents a valence electron.

These dots are arranged to the right and left and above and below the symbol, with no more than two dots on a side. For example, the representation for sodium is as follows: and the representation for chlorine is as follows: These diagrams are called Lewis electron dot diagrams, or simply Lewis diagrams, after Gilbert N. Lewis, the American chemist who introduced them. For the main group elements, the number of valence electrons is the same as the group number listed at the top of the periodic table. Lewis Diagrams of the Elements Lithium through Neon The transfer of electrons can be illustrated easily with Lewis diagrams. In the following diagram sodium transfers an electron to chlorine: In representing the final formula, the dots are omitted.

- Chemical Bonding: The Nature Of The Chemical Bond
Some ionic compounds have different numbers of cations and anions. In those cases, electron transfer occurs between more than one atom. The following diagram shows the formation of magnesium bromide from two bromine atoms and one magnesium atom: Most of the elements in ionic compounds form an ion that has a characteristic charge. Some elements, especially transition metals, can form ions with different charges. As we saw in Figure 3. Charges of Monoatomic Ions. Note that some atoms, especially transition metals, commonly form ions of different charges. This is due to internal orbital subshells that are very close to the valence shell and can be used in bond formation. Overall, ionic bonding occurs between a cation electron donor and an anion electron acceptor to form a compound that has an overall neutral net charge. Of note, ionic bonds usually occur between a metal and a nonmetal.

The compound formulas are written with the cation first followed by the anion, and the lowest ratio of cations and anions are used to create a net neutral compound. Bonds that occur between nonmetals with other nonmetals, or nonmetals with semi-metals or metalloids as they are also called , use covalent bonding, or the sharing of electrons, which is the topic of Section 3.

In this section, we will consider another type of bonding—covalent bonding. We will examine how atoms share electrons to form these bonds, and we will begin to explore how the resulting compounds, such as cholesterol, are different from ionic compounds. Covalent Bonds You have already seen examples of substances that contain covalent bonds. One substance was carbon dioxide CO2. You can tell from its formula that it is not an ionic compound; it is not composed of a metal and a nonmetal.

Consequently, its properties are different from those of ionic compounds. Note that the hydrogen atoms that are bonded to carbons within the molecule are not shown to save space. In Chapter 5, you will learn more about common shorthand techniques to draw complex organic molecules, like cholesterol. Electron Sharing Sections 3. Because most filled electron shells have eight electrons in them, chemists called this tendency the octet rule. But there is another way an atom can achieve a full valence shell: atoms can share electrons to reach the octet state or the duet state in the case of hydrogen. This concept can be illustrated by using two hydrogen atoms, each of which has a single electron in its valence shell. For small atoms such as hydrogen atoms, the valence shell will be the first shell, which holds only two electrons.
https://kpopcollege.com/kpopauditions.htm
- Chemical Bonds
We can represent the two individual hydrogen atoms as follows: In this situation neither hydrogen can reach the preferred duet state. In contrast, when two hydrogen atoms get close enough together to share their electrons, they can be represented as follows: By sharing their valence electrons, both hydrogen atoms now have two electrons in their respective valence shells.
