The elements which are characterised by the outer shell configuration `ns^(1)` to `n p^(6)` are colectively called

The elements that are characterised by the outer shell electronic configuration from ns^(1) to ns^(2) np^(5) are collectively called as:

The elements with similar outer shell configuration are placed in a __
