Question

hlo guys...which among the 3d series having the highest heat of atomization. .needed full explanation and concept....​

Answer 1

Answer:

Cr has the highest heat of atomization because it contains more unpaired electron (4s1 3d5)

Explanation:

The enthalpy of atomization depends on the extensive metallic bonding which in turn depends on the number of unpaired electrons

Answer 2

Sc & zn belongs to 3rd group pf periodic table. The extent ofmetallic bonding an elementundergoes decides the enthalpy of atomization. The more extensive the metallic bonding of an element, the more will be its enthalpy of atomization.

hope this helps u ❤️
