For example, during the formation of an ionic bond between sodium and chlorine atoms, sodium atom (1s 2 2s 2 2p 6 3s 1 ) has only one electron in its valence shell. By losing this one electron it complete its octet and acquires the noble gas configuration of neon (2, 8). While the chlorine atom..

Summary
Chlorine belongs to group VII A. Members of this group are called halogens which means 'salt producers'. Chlorine is a greenish yellow gas. Chlorine has seven electrons in its outer most shell and so has a valency of 1. Like other halogens chlorine is a strong oxidising agent. ..
