Answer 1

Answer:

How are the different energy levels represented ?

Explanation:

An energy level represents the 3-dimensional space surrounding the nucleus where electrons are most likely to be. ... When the third energy level has 8 electrons, the next 2 electrons go into the fourth energy level. The electrons in the energy level farthest from the nucleus are called valence electrons.
