Answer : Silicon dioxide, [tex]SiO_2[/tex], is a covalent compound.
Explanation :
Covalent compound : It is a compound in which the bonds are formed by the equal sharing of electrons. The bonds are formed between two non-metals.
Ionic compound : It is a compound in which the bonds are formed by the complete transfer of electrons.
In the silicon dioxide [tex](SiO_2)[/tex], the silicon and the oxygen atom is a non-metals and the bonds are formed between silicon and oxygen non-metal atoms are the covalent bonds.
Hence, the silicon dioxide, [tex]SiO_2[/tex], is a covalent compound.
