The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
Sulphur is not iso-electronic with any noble gas. However sulphide ion (S2- ion) is iso-electronic with argon with 18 electrons.
The element that will have a noble gas configuration by accepting two electrons from a magnesium atom is oxygen. By gaining two electrons, oxygen will achieve a stable octet configuration similar to that of a noble gas, fulfilling the octet rule.
A species (element, cation or anion) should have eight valence electrons to have a noble gas electronic configuration. However element upto atomic number 4 may have 2 valence electrons and attain the electronic configuration of helium noble gas.
Krypton is a noble gas with 36 electrons.
The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
A sulfur atom will gain 2 electrons to achieve a noble gas structure because sulfur is in group 16 of the periodic table and needs to fill its outer shell with a total of 8 electrons to become stable.

Helium is the element in the noble geses family that does not have an octet. Helium is the element in the noble geses family that does not have an octet.
An element can either gain or lose electrons to achieve a noble gas electron configuration. Such an electron configuration gives an atom of an element a full outer shell, thereby making that element's ion nonreactive. Metals tend to lose electrons, and become cations, whereas nonmetals tend to gain electrons, and become anions. The amount of electrons an element gains of loses is based on the group/family the element is found in on the Periodic Table.
To become like a noble gas, an element must have a full outer electron shell, making it stable and unreactive. Elements achieve this by gaining or losing electrons to reach a total of 8 electrons in their outer shell, like the noble gases.
Sulfur gains two electrons to achieve a stable noble gas electron configuration of argon. Sulfur has 16 electrons in its neutral state, and by gaining two electrons, it attains a full valence shell with eight electrons, similar to the nearest noble gas, argon.
Sulfur must to have an electrons octet.
