that depends on the number of electrons the more electrons the more energy
An electron in the outermost energy level of an atom is called a valence electron.(We refer here to the outermost occupied levels of an atom. There are, of course, many other higher energy levels normally available that are not occupied.)These electrons determine the chemical reactivity of the atom.the valence electrons
The period number tell about the energy levels occupied by electrons
two, i think recommend you check this answer not entirely sure
electrons
the period number tells which is the highest energy level occupied by the electrons
An atom's energy levels are orbitals which can contain 2 electrons each, assuming that they are traveling in opposite directions from each other.
the period number tells which is the highest energy level occupied by the electrons

Neon has the 1s2, 2s2, and 2p6 levels filled.
Electrons occupied certain discrete energy levels around the nucleus.

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
The period tells you how many energy levels an atom has.
