e) As
It is an element of the block d:
a) Rb
b) Sn
c) Pt
d) U
Solution
1. Ne has smallest atomic radius.
2. The smallest ionization is for Mg( Because it has large atomic size compared to remaining so
that we can take out one electron easily. The energy is called ionization energy)
3. Cl has more electronegativity value. Because it can easily takes electron and become negative.
4. Pt is D block element.
