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

Question

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

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

Step-by-Step Solution

Answer

Answer

(a)

Potassium's ground state electronic configuration is 1S²,2S²,2P⁶,3S²,3P⁶,4S¹.

Step 1: Configuration of the ground state electronic system

Aground-state configuration for an element is the electronic arrangement in which electrons reside with the least amount of energy in their lowest energy orbitals, whichever is possible.

Step 2: Ground-state electronic configuration of potassium

Potassium has an atomic number of 19 and is symbolizedbyK. Here is how potassium's electronic configuration looks at the ground state:

S²,2S²,2P⁶,3S²,3P⁶,4S¹.
