Subjective Type

The elements of $$3d$$ transition series are given as : $$Sc,\ Ti,\ V,\ Cr,\ Mn,\ Fe,\ Co,\ Ni,\ Cu,\ Zn$$ Which element is soft and why?

Solution

$$Zn$$, in $$Zn (3d^{10}4s^{2})$$ all the electrons present in $$d$$-orbitals are paired and hence metallic bonds present in it are weak. That is why, it is soft.

Hence $$Cu,\ Zn$$ are soft metals.
