Hi Queen!

What do you think?

anonymous · Answer

I am not sure... I know that the first level can hold 2 electrons, the second level can hold 8 electrons, and the third level can hold 18 electrons. The outermost electrons are called valence electrons. The valence electrons are those typically used in forming chemical bonds, as well as the fact that the energy travels OUT, rather than inwards, right?

Correct. To understand this question, let's take hydrogen atom as an example. H-atom is a simple atom with only one electron lying in the first orbital. Now what happens when we heat a hydrogen atom or provide energy to it?

Electrons absorb the energy and move to higher orbital or energy level which is away from the nucleus. Thus an electron has least energy when it is closest to the nucleus and vice versa.
