Question

An ionized atom has only a single electron. The n = 6 state of this atom has an energy of -9.444 eV. Find the radius of the n = 3 state.

Group of answer choices

0.233 nm

0.182 nm

0.0952 nm

0.204 nm

0.0317 nm

Answer 1

According to Bohr's model, the energy of the nth level of an atom is:

So, the energy for n = 6 will be:

So, the radius of this atom for n = 3 state will be:

Substituting the values of n and Z:
