Question

# If the valency shell electronic structure for an element is $$ns^{2} np^5$$, this element will belong to the group of:

A
alkali metals
B
inert metals
C
noble gases
D
halogens

Solution

## The correct option is C halogensThe valence shell or orbital electronic configuration of halogens(17th group elements) is $$ns^2\ np^5$$.Hence, the correct option is $$\text{D}$$Chemistry
