Answer #1

Answer) The answer will be option 'b'.

The magnisium ion has a higher Zeff charge, which causes greater attraction to the electrons and results in smaller atomic radius.

    This is a challenging multi-step problem. Solve it on paper, writing out each step carefully. When doing calculations, do not round intermediate values. Note: If you have approached the problem in a principled way, do not abandon your approach if your numerical answer is not accepted; check your calculations! The Bohr model correctly predicts the main energy levels not only for atomic hydrogen but also for other "one-electron" atoms where all but one of the atomic electrons has been removed,...
