Question

the energy of an electron in one-electron system can be calculated using the equation​

Answer 1

A simple expression for the energy of an electron in the hydrogen atom is:

• E=−13.6n2 where the energy is in electron volts.
• n is the principle quantum number.
• So for an electron in n=1 :
• E=−13.6eV.
• To convert to joules you can x this by 1.6×10−19.
