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

Question

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

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

(c)

Step-by-Step Solution

Answer

Answer

The ground state electronic configuration of aluminum is 1S²,2S²,2P⁶,3S²,3P¹  .

Step1: Electronic configuration

The filling of electrons in the orbitals follows the Aufbau principle, which states that lower energy orbitals are occupied first, followed by higher energy orbitals.

Step2: Ground-state electronic configuration of aluminum

The atomic number of aluminum is 13,and is symbolized by Al.The ground state electronic configuration of aluminum is represented as follows:

1S²,2S²,2P⁶,3S²,3P¹   .
