Why are the elements of groups IA and zero are called reactive element

1.	Why are the elements of groups IA and zero are called reactive elements and inert elements respectively?
Answer» Answer: The ELEMENTS of GROUP 1A have 1 VALENCE electron in their last shell and hence can lose an electron easily during compound formation, making them very reactive. The elements of zero group have a stable electronic configuration with their last shell complete and hence do not react easily with other elements to ATTAIN stable electronic configuration. Therefore, they are inert.

Answer:

The ELEMENTS of GROUP 1A have 1 VALENCE electron in their last shell and hence can lose an electron easily during compound formation, making them very reactive.

The elements of zero group have a stable electronic configuration with their last shell complete and hence do not react easily with other elements to ATTAIN stable electronic configuration. Therefore, they are inert.
