Question

what do you mean energy of electron is quantized​

Answer 1

Answer:

Electrons exist on specific energy levels and cannot exist in between them. When an electron moves to another energy level, it must release or absorb very specific amounts of energy. This is what quantized means: the amount of energy absorbed or released can only be specific quantities called quanta

Answer 2

Explanation:

1. Quantized energy means that the electrons can possess only certain discrete energy values; values between those quantized values are not permitted. ... Because of the quantized orbits, such “quantum jumps” will produce discrete spectra, in agreement with observations.
