Discuss why hardness and softness of
metals depend upon it's metallic
of bonding
?​

Answer 1

Answer:

By the electron-sea model, we might think that more electrons makes the bonds stronger, so hardness and melt point would increase across the periodic table. ... Filling the lower energy MOs (bonding MOs) makes the bonds stronger, which is why alkali metals have low melt points and are soft (not many bonding MOs filled).
