The correct statements about the energy levels of electrons in shells are the following:
- Each electron shell has a different energy level.
- The electron shells closer to the nucleus are of lower energy than those further away.
What are the energy levels of electrons?
They are the energy charge that an electron possesses, where in each period (in each shell) only a certain number of electrons fit.
Characteristics of energy levels of electrons
- Each orbit corresponds to an "energy level" and can only contain a strictly defined number of electrons.
- Within each energy level, electrons could be grouped into "sublevels," and each sublevel could only contain a given number of electrons.
- The electrons are placed in the different levels and sublevels in order of increasing energy until they are completed.
Therefore, we can conclude that the electrons of an atom have different energy levels, so they are classified by the energy level in which each of them is located.
