Chapter 11, Problem 3PE

Interpretation Introduction

Interpretation:

The electron configuration for chromium is to be stated.

Concept introduction:

Electronic configuration represents the arrangement of electrons in an atom. The sublevels are filled according to their increasing energy. The electrons are firstly filled into the sublevel having lowest energy. The sublevel closest to the nucleus has the lowest energy. The trend of filling of electrons according to the energy of sublevels is given below.
