Each of the following pairs of elements will react to form a binary ionic compound. Write the formula of each compound formed, and give its name. (c) Lithium and nitrogen

Key Concepts

Ionic Compounds

Ionic compounds are formed when atoms transfer electrons, resulting in the formation of positively charged cations and negatively charged anions. These oppositely charged ions attract each other, creating a stable compound. Understanding the nature of ionic bonds is essential for predicting the formulas and names of the resulting compounds.

Valence Electrons

Valence electrons are the outermost electrons of an atom and play a crucial role in chemical bonding. The number of valence electrons determines how an element will react and what type of ions it will form. For lithium, which has one valence electron, it will lose that electron to form a cation, while nitrogen, with five valence electrons, will gain three electrons to form an anion.

Chemical Nomenclature

Chemical nomenclature is the system of naming chemical compounds based on their composition and structure. For ionic compounds, the name typically consists of the cation name followed by the anion name, with the anion often modified to end in '-ide.' In the case of lithium and nitrogen, the resulting compound is lithium nitride, reflecting the ions formed during the reaction.
