Each sodium ion is surrounded by six chloride ion, and each chloride ion is surrounded by six sodium ions (it has 6:6 coordination). Each molecule comprises two iodine atoms joined by a covalent bond. The molecules in solid iodine form a regular array with weak van der Waal's forces between molecules.
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs and the stable balance of attractive and repulsive forces between atoms when they share electrons is known as covalent bonding.n the molecule H 2, the hydrogen atoms share the two electrons via covalent bonding. Covalency is greatest between atoms of similar electronegativities. Thus, covalent bonding does not necessarily require that the two atoms be of the same elements, only that they be of comparable electronegativity.
