How Does the Energy of an Electron Relate with the Distance

Question

How does the energy of an electron relate with the distance from the nucleus?  
A) The closer an electron is from the nucleus, the greater its energy.
B) The farther an electron is from the nucleus, the greater its energy.
C) The farther a proton is from the nucleus, the greater the electron's energy.
D) The closer a proton is from the nucleus, the greater the electron's energy.
E) The closer a neutron is from the nucleus, the greater the electron's energy.

Accepted Answer

The energy of an electron is inversely proportional to its distance from the nucleus. The farther an electron is from the nucleus, the greater its energy. This is because the attraction between the positively charged nucleus and negatively charged electrons decreases as the distance between them increases. Therefore, the energy required to remove an electron from an atom decreases as the distance from the nucleus increases.
