Answer 1

Answer:

ions are the electrically charged atoms. An ion is an atom that can be positively or negatively charged. A negatively charged ions are called anion and positively charged ion are called cation

EXAMPLE

SODIUM ION Sodium (Na+)

electronic configuration = K = 2, L = 8 , M = 1

So to complete its octet the Sodium will loose 1 electron to the valency of the Sodium will be 1 and it will become positively charged ion which is cation
