Question

If the valence shell electronic structure is ns² np², the element will belongs to the group of
a) alkali metals
b) halogens
c) alkaline earth metals
d) actinoids

Answer 1

if the velence shell electronic structure is ns2 np2 , the elements will belong to the group of alkaline earth metals .
option (c) is correct
it includs group 3rdA and 4rthA.

Answer 2

Hey dear,

◆ Answer -

None of the above

Gr. 14 (Carbon family) is the correct answer.

◆ Explanation -

- Valence shell electronic configuration ns2 np2 is shown by gr.14 elements i.e. carbon family.

- For example,

[C] = [He] 2s2 2p2

[Si] = [Ne] 3s2 3p2

# For the options -

a) Alkali metals => ns1

b) Halogens => ns2 np5

c) Alkaline earth metals => ns2

d) Actinoids => 5f0-14 6d0-2 7s2

Hope this helped you. Thanks for asking..
