Write the ground state electron configurations for the following atom. Chromium (Cr) Determine the total number of unpaired electrons. Determine the magnetic properties (paramagnetic or diamagnetic).

6 unpaired electrons

paramagnetic

Explanation:

Paramagnetic are those which has unpaired electrons and diamagnetic are those in which all electrons are paired.

Given, Chromium (Cr) the atomic number - 24

The electronic configuration is -  

There are 5 unpaired electrons in 3d and 1 unpaired in 4s. Total number of unpaired electrons = 6

Thus, the element is paramagnetic as the electrons are unpaired.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
