Understanding Ionic Compounds

Ionic compounds are formed when two or more elements with different electronegativities combine to form a chemical bond. This bond is typically between a metal and a nonmetal. The metal loses one or more electrons to become a positively charged ion, known as a cation, while the nonmetal gains one or more electrons to become a negatively charged ion, known as an anion. The resulting compound is composed of the cation and anion in a fixed ratio, which is determined by the charges of the ions.

Determining the Formula for Chloride

The first compound listed is chloride. Chloride is a binary compound composed of chlorine and hydrogen. Chlorine is a nonmetal that typically forms a -1 charge, while hydrogen is a nonmetal that typically forms a +1 charge. However, in the case of chloride, the formula is Cl2, which suggests that the chlorine is in its elemental form, rather than as a chloride ion. This is because the chlorine is not combined with hydrogen to form a chloride ion.

However, the formula Cl2 is not the correct formula for chloride. Chloride is typically represented by the formula Cl-, which indicates that the chlorine is in its ionic form. Therefore, the correct formula for chloride is Cl-.

Determining the Formula for Lithium Nitride

The second compound listed is lithium nitride. Lithium is a metal that typically forms a +1 charge, while nitrogen is a nonmetal that typically forms a -3 charge. The formula Li3N suggests that the lithium is in its ionic form and that the nitrogen is also in its ionic form. However, the charges of the ions must be balanced in order to determine the correct formula.

To determine the correct formula, we must consider the charges of the ions. Lithium has a +1 charge, while nitrogen has a -3 charge. In order to balance the charges, three lithium ions are required to balance the charge of one nitrogen ion. Therefore, the correct formula for lithium nitride is Li3N.

Conclusion

In conclusion, the correct formula for chloride is Cl-, while the correct formula for lithium nitride is Li3N. These formulas are determined by the charges of the ions and the fixed ratio in which they combine to form the compound.
