Find the radius and energy of ion in the states

A. n=1 B. n=4 C. n=10


As we know that radius of an atomic orbit is given by,




Again, the energy of the atomic orbit is given as,



Here Z is the atomic number of the atom. Thus Z for is 2.


A. Here, n=1 and thus the radius and energy becomes,



And energy,


B. here n=4 and thus the radius and energy is,



And energy,


C. here n=10 and thus the radius and energy becomes,



And energy is,
