Question

Write the full ground-state electron configuration for each:
(a) Rb (b) Ge (c) Ar

Answer 1

(a) Rb

`1s^22s^22p^63s^23p^63d^(10)4s^24p^65s^1`

(b) Ge

`1s^22s^22p^63s^23p^63d^(10)4s^24p^2`

(c) Ar

`1s^22s^22p^63s^23p^6`

Step-by-step explanation:

(a) Rb

Atomic number = 37

The electronic configuration is -

`1s^22s^22p^63s^23p^63d^(10)4s^24p^65s^1`

(b) Ge

Atomic number = 32

The electronic configuration is -

`1s^22s^22p^63s^23p^63d^(10)4s^24p^2`

(c) Ar

Atomic number- 18

The electronic configuration is -

`1s^22s^22p^63s^23p^6`
