Magnesium nitrate contains chemical bonds that are
a) covalent, only
b) ionic, only
c) both covalent and ionic
d) neither covalent nor ionic

Answer : The correct option is, (C) both covalent and ionic

Explanation :

Ionic bond : It is defined as the bond that is formed by complete transfer of electrons from one atom to another atom.

That means, the atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom.

The ionic bond is usually formed between a metal and a non-metal.

Covalent bond : It is defined as the bond which is formed when sharing of electrons takes place between the atoms.

This is usually formed between two non-metals.

As we know that in magnesium nitrate, the magnesium is the metal having the atomic number 12 and belongs to group 2. The symbol of magnesium is, (Mg). The stable oxidation state of magnesium is (+2).

The element nitrate is the non-metal polyatomic ion. The stable oxidation state of nitrate ion is, (-1).

When the magnesium combine with the nitrate ion, it forms magnesium nitrate.

Magnesium nitrate contains both covalent and ionic bonds.

An ionic bond formed between the magnesium metal and nitrate ion.

A covalent bond formed between the nitrogen and oxygen non-metal.

Hence, the correct option is, (C) both covalent and ionic
