9^F^19 = 1s^2 2s^2 2p^2x 2p^2y 2p^1z

16^S^32 = 1s^2 2s^2 2p^6 3s^2 3p^2x 3p^1y 3p^1z

18^Ar^38 = 1s^2 2s^2 2p^6 3s^2 3p^6  

(i) Max. nuclear charge =18 in .18^Ar^38

(ii) Minimum no. of neutrons =10 in .9^F^19

(iii) Maximum no. of unpaired electrons =2 in .16^S^32

Hope it helps...

Answer:

a) {}^{38}_{18} Ar

b) {}^{19}_9 F

c) {}^{32}_{16}S

Given:

{}^{19}_9 F , {}^{32}_{16}S, {}^{38}_{18} Ar are three given elements.

Find:

The electronic configuration of the elements given.

Solution:

1. {}^{19}_9 F  (Fluorine)

Atomic number, Z = 9

Mass number, A = 19

Number of electrons = Number of protons = Z = 9

Number of neutrons = A - Z = 19 - 9 = 10

Nuclear Charge = Number of protons×e = +9e

Electronic configuration = 1s² 2s² 2p⁵

Unpaired electrons = 1

2. {}^{32}_{16} S (Sulphur)

Atomic number, Z = 16

Mass number, A = 32

Number of electrons = Number of protons = Z = 16

Number of neutrons = A - Z = 32-16 = 16

Nuclear Charge = Number of protons×e = +16e

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

Unpaired electrons = 2

3. {}^{38}_{18} Ar (Argon)

Atomic number, Z = 18

Mass number, A = 38

Number of electrons = Number of protons = Z = 18

Number of neutrons = A - Z = 38 - 18 = 20

Nuclear Charge = Number of protons×e = +18e

Electronic configuration = 1s² 2s² 2p⁶ 3s² 3p⁶

Unpaired electrons = 0

a) Ar has the maximum nuclear charge. (+18e)

b) F has the minimum number of neutrons. (10)

c) S has the maximum number of unpaired electrons. (2)
