Question

Write the equation for calculating the energy absorbed or emitted by an electron when it

moves from one orbital to another.​

Answer 1

Using the formula, we can calculate how much energy is absorbed/released during the transition of an electron. The energy change during the transition of an electron from n = n 1 n=n_1 n=n1 to n = n 2 n=n_2 n=n2 is Δ E = E 2 − E 1 = 13.6 × ( 1 n 1 2 − 1 n 2 2 ) eV .
