Dear Student,

1) They both are isoelectronic species Therefore only charge will
decide the size of atom Greater the negative charge, greater will
the size of anion Therefore,
O2- > F-

2) Size of atom increases on going from top to bottom in a group
due to decrease in effective nuclear charge Therefore,
As > P
