Explanation

• In atomic physics, the energy of an electron in an atom is quantized, meaning it can only take on specific discrete values.
• This is a fundamental principle of quantum mechanics, which states that energy is not continuous, but rather comes in small, discrete packets (quanta).
• The energy levels of electrons in an atom are determined by the solutions to the Schrödinger equation, and they are characterized by specific energy values, known as energy eigenvalues.
• These energy levels are quantized, meaning they can only take on specific values, and not any arbitrary value.
