11. What is the ground state electron configuration for the Fe2+ ion?а. [Ar] 4s23d4b. [Ar] 3а6c. [Ar] 4s?3d6d. [Ar] 3d812. Why does Na have a smaller radius than Rb?a. Na has more electrons than Rbb. Na has more protons and thus a higher effective nuclear chargec. Rb has more protons and thus a higher effective nuclear charged. Rb has more shells than Na so the valence electrons are farther removedfrom the nucleus 9. Each of the following gases occupy identical volumes at STP. Which ofthe following statements is not correct?НеХеNea. The density of each gas is the sameb. The average kinetic energy of each gas is the samec. Each flask has the same number of gas atomsd. There are and equal number He and Xe atoms10. Which of the following atoms is diamagnetic in the ground state?a. 0b. Fc. Ned. Na

Atomic radius is defined as the distance from the centre of nucleus to outermost shell of atom.
