Yes, the occupied energy level changes. The number of shells increases down the group.
electrons
2
the period number tells which is the highest energy level occupied by the electrons
hi
the period number tells which is the highest energy level occupied by the electrons
i don't the answer
that depends on the number of electrons the more electrons the more energy
An atom's energy levels are orbitals which can contain 2 electrons each, assuming that they are traveling in opposite directions from each other.
Electrons occupied certain discrete energy levels around the nucleus.
