5 Questions
What is the valence shell electronic configuration of these elements?
ns 2 np 3
Why is the electronic configuration of these elements extra stable?
The s orbital is completely filled and p orbitals are half-filled
What happens to the covalent and ionic radii down the group?
They increase in size
Why is there only a small increase in covalent radius from As to Bi?
Due to the presence of completely filled d and/or f orbitals in heavier members
What happens to the ionisation enthalpy down the group?
It decreases due to gradual increase in atomic size
