Hypothetical Element X

Excited Electron

Energy of 12 eV

Excited Electron

Energy of 4 eV

Ground State

Energy of 1 eV

When electron falls back to ground state, what energies
is it capable of giving off?

Answer

8 eV, 3 eV, 11 eV

(the difference between
each possible energy level)

1 eV = 1.6 x 10^-19 J
