The electron configuration of a neutral magnesium atom is: 1s2 2s2 2p6 3s2 or in shorthand [Ne] 3s2.
Magnesium has 2 valence (outer-shell) electrons and will lose both to fulfill the octet rule, becoming Mg2+. The ion's configuration would therefore be: 1s2 2s2 2p6, which is isoelectronic with neon, so it can also be represented as [Ne].
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
The ground-state electron configuration for a neutral atom of manganese is: 1s22s22p63s23p63d54s2 or [Ar]3d54s2
Calcium has the electron configuration [Ar]4s2; the neutral atom of calcium has 20 electrons.
The electron configuration for a neutral potassium atom is 1s2 2s2 2p6 3s2 3p6 4s1. This configuration represents the arrangement of electrons in the energy levels around the nucleus of the potassium atom.
An atom with 12 electrons, such as a neutral magnesium atom, will contain 2 electrons in its first energy level, 8 electrons in its second energy level, and 2 electrons in its third energy level. The electron configuration table for magnesium would look like this: 1s2 2s2 2p6 3s2 For the atom of magnesium to become "stable," it would have to lose those two valence electrons in its outermost shell by forming an ionic bond with another atom, thus becoming a magnesium ion with a -2 charge, written as Mg-2.
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.

Calcium has the electron configuration [Ar]4s2; the neutral atom of calcium has 20 electrons.
The electron configuration for a neutral atom of chlorine is 1s2 2s2 2p6 3s2 3p5. Chlorine has 17 electrons, and this configuration indicates the distribution of those electrons in its various energy levels.

That electron configuration represents the electron arrangement of a neutral atom of magnesium (Mg), which has 12 electrons. It shows the distribution of electrons in various energy levels or shells: 1s2, 2s2, 2p6, and 3s2.
The element magnesium (atomic number 12) has the electron configuration of1s2 2s2 2p6, 3s2or the noble gas abbreviation [Ne] 3s2(see related link)The electron configuration for neutral magnesium (Mg) is 1s22s22p63s2. The ion, Mg2+, has two electrons fewer, so the outer two electrons are removed from the electron configuration. This changes the electron configuration to 1s22s22p6, which is the same electron configuration as the noble gas neon.
There are 2 electrons in the valence orbital of a Magnesium atom.
