Question

Explain why the metal metal bonding is more frequently found with the second and third series of transition elements

Answer 1

Ad they are ionic in nature..

Answer 2

Hey dear,

● Explanation -
- 4d and 5d elements are comparatively larger than those of 3d elements.
- They have higher enthalpies of atomization.
- Valence electrons in these elements are loosely bound and easily forms M-M bond.
- Hence, 2nd and 3rd series of transition elements show metal-metal bonding frequently.


Hope this helps you...
