IE of `Li^(-)` will be more than `Na^(-)`?

Ionic mobility of Li^(+) is less than Na^(+) and K^(+) because

If c=50,backslash the value of a+b+c will be more than 50 but less than 100 more than 100 but less than 103 more than 103 but less than 105 more than 10

IE_(1) value of Mg is more than that of Na while it’s IE_(2) value is less. Explain.

Assertion (A): Li^(o+) (aq) has large ionic redius than Na^(o+) (aQ). Reason (R ): Li^(o+) (aq) is relatively more hydrated as compared to Na^(o+) aq.

Mg^(2+) ion more highly hydrated than Na^(+) ion.

Statement-I : IE_(3) of Mn is more than IE_(3) of Fe. Statement-II : After the removal of 2 electron Fe acquire half filled electronic configuration.

I.E. for cation is more than neutral atom. Why?

Assertion (A): CuCI is more covalent than NaCI . Reason (R ): Na^(o+) ion more polarising than Cu^(o+) ion.
