These compounds are all ionic structures, which means they’re formed from one metal and one non metal ion. Usually, in the chemical formulas of these ionic compounds, the metal ion is in front of the non metal ion. When you identify the non metals (or metals), make sure you give their element name, instead of their ion name. (Eg in MgO, the ion names are magnesium and oxide ion, but the elements are magnesium and oxygen.)

Therefore, MgO, magnesium oxide, the non metal is oxygen.

NaH, sodium hydride, non metal is hydrogen.

For the third one, i suppose you’re looking for AlBr3, because aluminum and boron are both metals and metalloids and they do not form an ionic bond. So, if you’re looking for AlBr3, aluminum bromide, the non metal is bromine.

And for FeS, iron (ii) sulphide, the nonmetal is sulphur.

A compound is a substance made up of many components linked by a chemical connection.

MgO = Magnesium Oxide

NaH = Sodium Hydride

AlBr3 = Aluminum Bromide

FeS = Iron (ii) Sulphide

What are the Ionic compounds?

These are all ionic structures, meaning they're made up of one metal and one non-metal ion.

The metal ion is usually in front of the nonmetal ion in the chemical formulae of these ionic compounds.

Make sure to give their element name instead of their ion name when identifying nonmetals (or metals).

For example, the ions magnesium and oxide ion are named after the elements magnesium and oxygen in MgO, although the elements are magnesium and oxygen.

  • The nonmetal is oxygen, and the metal is magnesium oxide.
  • Nonmetal is hydrogen in the form of sodium hydride (NaH).
  • Because aluminum and boron are both metals and metalloids with no ionic link, AlBr3 is formed. Bromine is the nonmetal in AlBr3, aluminum bromide.
  • Sulphur is the nonmetal in FeS, iron (ii) sulphide.
