Explanation / Answer

A)

Number of electron in Ca = 20

Electronic configuration is 1s2 2s2 2p6 3s2 3p6 4s2

Noble gas having lesser electron than Ca and closest to it is Argon (Ar)

Number of electron in Ar = 18

electronic configuration of Ar is: 1s2 2s2 2p6 3s2 3p6

So, electronic configuration of Ca in noble gas form is:

[Ar]4s^2

B)

Number of electron in Si = 14

Electronic configuration is 1s2 2s2 2p6 3s2 3p2

Noble gas having lesser electron than Si and closest to it is Neon (Ne)

Number of electron in Ne = 10

electronic configuration of Ne is: 1s2 2s2 2p6

So, electronic configuration of Si in noble gas form is:

[Ne]3s^23p^2

C)

Number of electron in S = 16

Electronic configuration is 1s2 2s2 2p6 3s2 3p4

Noble gas having lesser electron than S and closest to it is Neon (Ne)

Number of electron in Ne = 10

electronic configuration of Ne is: 1s2 2s2 2p6

So, electronic configuration of S in noble gas form is:

[Ne]3s^23p^4

D)

Number of electron in Ga = 31

Electronic configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p1

Noble gas having lesser electron than Ga and closest to it is Argon (Ar)

Number of electron in Ar = 18

electronic configuration of Ar is: 1s2 2s2 2p6 3s2 3p6

So, electronic configuration of Ga in noble gas form is:

[Ar]3d^104s^24p^1
