To determine whether a compound is ionic or covalent, we need to consider the types of elements involved. Ionic compounds typically consist of metals and nonmetals, while covalent compounds are usually formed between nonmetals.<br /><br />1) **$Na_{2}CO_{3}$**: This is an ionic compound because it consists of sodium (a metal) and the carbonate ion (a polyatomic ion). The name is Sodium Carbonate.<br /><br />2) **$P_{2}O_{5}$**: This is a covalent compound as it consists of nonmetals phosphorus and oxygen. The name is Diphosphorus Pentoxide.<br /><br />3) **$NH_{3}$**: This is a covalent compound made up of nitrogen and hydrogen, both nonmetals. The name is Ammonia.<br /><br />4) **$FeSO_{4}$**: This is an ionic compound consisting of iron (a metal) and the sulfate ion (a polyatomic ion). The name is Iron(II) Sulfate.<br /><br />5) **$SiO_{2}$**: This is a covalent compound composed of silicon and oxygen, both nonmetals. The name is Silicon Dioxide.<br /><br />6) **$GaCl_{3}$**: This is an ionic compound because it consists of gallium (a metal) and chlorine (a nonmetal). The name is Gallium Chloride.<br /><br />7) **$CoBr_{2}$**: This is an ionic compound consisting of cobalt (a metal) and bromine (a nonmetal). The name is Cobalt(II) Bromide.<br /><br />8) **$B_{2}H_{4}$**: This is a covalent compound made up of boron and hydrogen, both nonmetals. The name is Diborane.<br /><br />9) **$\infty$**: This symbol does not represent a chemical compound, so it cannot be classified as ionic or covalent, nor can it be named as such.
