Q.1-1-23b - Organic Chemistry (Mcmurry)

Question

Give the ground-state electron configuration for each of the following elements:

        (a) Potassium (b) Arsenic (c) Aluminum (d) Germanium

(b)

Step-by-Step Solution

Answer

Answer

The ground state electronic configuration of arsenic is

1S²,2S²,2P⁶,3S²,3P⁶,4S²,3d¹⁰,4p³.

Step1: Stable electronic configuration

The half-filled and full-filled ground state electronic configuration of any element is the most stable configuration.

Step2: Ground-state electronic configuration of arsenic

The atomic number of arsenic is 33 and it is symbolized as As.The ground state electronic configuration of arsenic is represented as follows:

 .1S²,2S²,2P⁶,3S²,3P⁶,4S²,3d¹⁰,4p³.
