Find the radius and energy of ion in the states A. n=1 B. n=4 C. n=10

Question

Philoid · Accepted Answer

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,
