Which electrons have the greatest binding energy?

• N-shell

• M-shell

• L-shell

• K-shell

Answer explanation

The K shell electron is located closest to the nucleus and has the highest energy level and the greatest binding energy. The M, N, and L shell electrons are located farther from the nucleus.
