A singly ionized helium atom has an electron in the n = 4 state. What is the **kinetic** energy of the electron?

Step 1

The total energy of an electron in a Helium atom can be calculated as follows.

Step 2

According to viral theorem, potential energy is equal to negative twice the kinetic energy for bound system in which potential inversely proportional to distance.

The viral theorem for Helium atom is given below.

Step 3

Therefore, kinetic energy is equal to negative total ener...
