The quantized property of an electron among the options you've provided is: C) Energy
What is meant by a quantized property of an electron?
In an atom, electrons exist in discrete energy levels or shells. They can move between these levels by absorbing or emitting specific amounts of energy, thus demonstrating the quantized nature of electron energy.
Electron charge is constant and not quantized. Every electron has the same negative charge (-e).
Nuclear Charge refers to the charge of the nucleus, which is due to protons. It is not a property of the electron itself.
