a) Nuclear charge(Z)
b) valence principal quantum number(n)
c) election-election intraction in outer orbitals
d) none of the factors because their size is the same.
Ans:- a {Nuclear charge(Z)}
the size of isoelectronic species cl- ar and ca2+ is affected by
Ans:-The size of isoelectronic is affected by atomic number means if we increase atomic number of isoelectronic then size is also decrease s.
