An atom of magnesium has 3 energy levels - the first energy level can hold up to 2 electrons, the second can hold up to 8 electrons, and the third can hold up to 18 electrons.
Arsenic has 8 levels of energy.
Technetium has five electron shells.
The magnitude of the energy change in the process of Mg turning into Mg+ is the ionization energy, which is the amount of energy required to remove an electron from a neutral atom to form a singly charged ion (Mg+). This process is endothermic, meaning it requires energy input.

The period number is equal to the number of energy levels. Elements of period 3 have 3 energy levels. Na,Mg,Al,Si are few elements in the period 3.
Magnesium (Mg) has two electrons in it's lowest (s) orbital.
An atom of magnesium has 3 energy levels - the first energy level can hold up to 2 electrons, the second can hold up to 8 electrons, and the third can hold up to 18 electrons.
Bromine has FOUR energy Levels.
Arsenic has 8 levels of energy.
Germanium has 4 energy levels.
Chlorine has three energy levels.
There are 3 energy levels in Silicon. Which ever row it is in the Periodic Table, that is how many energy levels it has. The structure is 1s2 2s22p63s23p2
The number of energy levels in the 3s conduction band of a single crystal of sodium weighing 26.8 mg is enormous, on the order of Avogadro's number (6.022 x 10^23). This is due to the large number of atoms present in the crystal. Each sodium atom has one electron in its 3s orbital, leading to a vast number of energy levels in the conduction band.
Germanium has 4 energy levels.
Iodine has seven energy levels.
Xenon has 6 energy levels.
