This corresponds to the electronic configuration; [Ne] 3s2. This electronic configuration belongs to magnesium.
What is neutral Atom?
When an atom has an equal numeral of electrons and protons, it has an equivalent number of negative (the electrons) and positive electric charges (the protons). As a result, the atom's total electric charge exists at zero, and it stands stated to be neutral. Therefore, all the elements in the periodic table exist as neutral atoms.
The number of electrons on a neutral atom stands equal to the number of protons in the nucleus of the atom. This is understood as the atomic number, Z. The removal or addition of electrons to a neutral atom forms ions that maintain a net negative or positive charge.
The neutral atom that holds its first two energy levels filled, has 2 electrons in its third energy level and includes no other electrons exist magnesium. Electrons in atoms exist positioned in energy levels. These energy levels are equal to shells in the Bohr model of the atom.
The atom thus expressed in the question contains its first and second energy levels filled and two electrons in the third level. This corresponds to the electronic configuration; [Ne] 3s2. This electronic configuration belongs to magnesium.
