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 -  

[tex]1s^22s^22p^63s^23p^63d^{5}4s^1[/tex]

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.
