[Ne] 3s2
The noble gas configuration of magnesium is [Ne] 3s^2. This indicates that magnesium has the same electron configuration as the nearest noble gas, neon, with an outer shell containing 2 electrons in the 3s orbital.
The noble gas that has the same electron configuration as magnesium ion (Mg²⁺) is neon (Ne). When magnesium loses two electrons to form Mg²⁺, it has the electron configuration of 1s² 2s² 2p⁶, which is identical to that of neon. Thus, both Mg²⁺ and Ne have a complete octet in their outer shell.

The "Noble gas electron configuration," or the condensed electron configuration, for F is [He] 2s2 3p5.
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.
The noble gas configuration of Mg2+ is [Ne] because the magnesium atom loses two electrons to form the Mg2+ ion. The electron configuration of Ne is 1s2 2s2 2p6, so when Mg loses its two valence electrons, it achieves a stable electron configuration similar to that of the noble gas Ne.
The noble gas electron configuration of radon is [Xe]4f145d106s26p6.
The element with the noble-gas configuration Ne 3s2 is sodium (Na). Sodium has an electron configuration of 1s2 2s2 2p6 3s1, but when it loses one electron, it attains the stable electron configuration of neon by having 2 electrons in the 3s orbital.
No, chlorine (Cl) does not have a noble gas electronic configuration. It has the electron configuration [Ne]3s^2 3p^5, which is one electron away from achieving a stable, noble gas configuration like argon (Ar).
A noble gas electron configuration involves representing an element's electron configuration by using the electron configuration of the nearest noble gas preceding it in the periodic table, followed by the remaining electron configuration for that element. For example, the noble gas electron configuration for sodium (Na) is [Ne] 3s¹, where [Ne] represents the electron configuration of neon leading up to sodium.
The electron configuration of boron is: [He]2s2.2p1.
