Ne, `Na^(+)` and `F^(-)` have the same

Assertion :Bothe Cu^(+) and Na^(+) have almost same radil. Reason : Cu^(+) possesses more power to polarise an anion.

Na^+ and:Ne have the same number of electrons but the ionization potential of Na is 47.3 eV arid that of Ne only 21.6 eV. Why?

Out of N, O, Ne, Na, Na^(+) select the species which have maximum and minmum ionization energy.

Out of N, O, Ne, Na, Na^(+) select the species which have maximum and minimum ionization energy.

Which out of Na^(+) and Ne has higher ionisation potential?Explain with reson.

The Ne atom has 10 times the mass of H_(2) molecule. Which of the following statements is true? I. At 25^(@)C both of them have the same kinetic energy. II. Ten moles of H_(2) would have the same volume as 1 mole of Ne at same temp. and pressure. III. One mole of Ne exerts the same pressure as one mole of H_(2) at STP. IV. A H_(2) molecule travels 10 times faster than Ne atom at same temperature. V. At STP, one litre of Ne has 10 times the density of 1 litre of H_(2).
