Solution
The correct option is A Metallic bond Atoms of calcium in a crystal of calcium has metallic bonds.
Metallic solids are the crystalline solids formed by atoms of an metallic element. The bonding electrons forms a sea of electrons over crystal lattice and can freely move from one end to other. The metal ions form a kernel with sea of electrons around it.
Metallic bonding is formed from the electrostatic force between the positively charged metal kernels and delocalised conduction electrons.
