3 The electron of one atom are shared between two atoms
4 None of the above
Explanation:
The covalency of an atom is the number of electron it shares with the other atoms when forming chemical bonds. Usually but not always, it is the number of covalent bonds it forms with the other bonds. Example: In \(CH _4\), carbon shares its four electrons with four electrons of four different \(H\) - atoms to form \(4\) covlent bonds. Hence covalency of carbon is \(4.\)

1 Covalent
2 Ionic
3 Metallic
4 Coordinate
Explanation:
(a) In graphite all carbon atoms are \(s{p^2}\)-hybridised and have covalent bond.

Which of the following substances has giant covalent structure
1 Iodine crystal
2 Solid \(C{O_2}\)
3 Silica
4 White phosphorus
Explanation:
(c) Silica has tendency to form long chain covalent structure such as carbon so it has giant covalent structure.
