उत्तर
Cl : halogen group : : Ar : zero group
Explanation:
Elements are classified into groups based on their chemical properties and valence electron configurations:
- Chlorine (Cl) belongs to Group 17, which is known as the halogen group.
- Argon (Ar) belongs to Group 18, which is known as the zero group (or noble gas group) because its atoms have a stable, octet electron configuration, resulting in a valency of zero.
