$N^{3-} , Na^+ ,F^- , Mg^{2+}$ and $O^{2-}$ ની આયનીય કદ નો સાચો ક્રમ કયો છે ?

Q: $N^{3-} , Na^+ ,F^- , Mg^{2+}$ and $O^{2-}$ ની આયનીય કદ નો સાચો ક્રમ કયો છે ?

c Ionic size increases with the addition of electrons and ionic size decreases with the loss of electrons. The nitride ion, has $10$ electrons in contrast to only $7$ protons. It has high inter electronic repulsions due to which it has the maximum size. The increasing order of ionic size is $Mg ^{2+}\,<\, Na ^{+}\,<\,F ^{-}\,< \,O ^{2-}$ They are isoelectronic species with same number of electrons. Higher is the atomic number, higher will be the effective nuclear charge, lower will be the size.

Question

A$Mg^{2+} > Na^+ > F^- > O^{2-} < N^{3-}$
B$N^{3-} < F^- > O^{2-} > Na^+ > Mg^{2+}$
C$Mg^{2+} < Na^+ < F^- < O^{2-} < N^{3-}$
D$N^{3-} > O^{2-} > F^- > Na^+ < Mg^{2+}$

Solution

c
Ionic size increases with the addition of electrons and ionic size decreases with the loss of electrons. The nitride ion, has $10$ electrons in contrast to only $7$ protons. It has high inter electronic repulsions due to which it has the maximum size. The increasing order of ionic size is $Mg ^{2+}\,<\, Na ^{+}\,<\,F ^{-}\,< \,O ^{2-}$

They are isoelectronic species with same number of electrons. Higher is the atomic number, higher will be the effective nuclear charge, lower will be the size.
