By Fajans' rule,
Smaller the size of cation, larger the size of anion. Larger the charge on cation or anion, larger the polarising power and thus, greater the covalent nature.
NaF, Na2O, Na3N, Na+ is same.
Smaller the size of cation, larger the size of anion. Larger the charge on cation or anion, larger the polarising power and thus, greater the covalent nature.
NaF, Na2O, Na3N, Na+ is same.

Covalent nature of NaF, Na2Oand Na3N in the increasing order isa)Na3N ...
Covalent nature of NaF, Na2O, and Na3N in the increasing order is:
NaF, Na2O, Na3N
Explanation:
Covalent nature refers to the extent of sharing of electrons between atoms in a compound. In general, covalent compounds are formed between two nonmetals or a metal and a nonmetal.
NaF:
- Sodium fluoride (NaF) is an ionic compound.
- Sodium (Na) is a metal, and fluoride (F) is a nonmetal.
- In ionic compounds, electrons are transferred from the metal to the nonmetal, resulting in the formation of ions.
- NaF is formed by the transfer of one electron from sodium to fluorine, resulting in the formation of Na+ and F- ions.
- The electrostatic attraction between the positive and negative ions holds the compound together.
- Since NaF is an ionic compound, it has a high melting and boiling point and conducts electricity when molten or in aqueous solution.
- Therefore, NaF has the least covalent nature among the given compounds.
Na2O:
- Sodium oxide (Na2O) is also an ionic compound.
- Sodium (Na) is a metal, and oxygen (O) is a nonmetal.
- Na2O is formed by the transfer of two electrons from two sodium atoms to one oxygen atom, resulting in the formation of 2 Na+ and O2- ions.
- The electrostatic attraction between the positive and negative ions holds the compound together.
- Like NaF, Na2O also has a high melting and boiling point and conducts electricity when molten or in aqueous solution.
- However, Na2O has a slightly higher covalent nature compared to NaF because it involves the sharing of two electrons between sodium and oxygen atoms.
Na3N:
- Sodium nitride (Na3N) is a covalent compound.
- Sodium (Na) is a metal, and nitrogen (N) is a nonmetal.
- In covalent compounds, electrons are shared between atoms to form bonds.
- Na3N is formed by the sharing of three electrons between sodium and nitrogen atoms, resulting in the formation of a covalent bond.
- Covalent compounds have lower melting and boiling points compared to ionic compounds.
- Na3N has the highest covalent nature among the given compounds since it involves the sharing of three electrons.
Therefore, the increasing order of covalent nature is NaF < na2o="" />< na3n.="" />
