[He]2s22p4
The noble gas configuration for oxygen is [He] 2s2 2p4, which means that it has the same electron configuration as neon except with two additional electrons in the 2p orbital. This configuration reflects the stable arrangement of electrons in the outer shell of oxygen, similar to a noble gas.
The noble gas configuration of oxygen (O) is [He] 2s^2 2p^4, where [He] represents the electron configuration of the nearest noble gas, helium.

Neon --- Closest noble gas on the periodic table.
The noble gas that has the same electron configuration as the oxygen atom in a water molecule is neon (Ne). Both have a full valence shell with 8 electrons, making them stable and unreactive.
There is no noble gas with the same electronic configuration as the element barium (Ba). But Ba2+ ion and the noble gas xenon (Xe) will have the same number of electrons (54 electrons each).
Yes it is possible to write the noble gas configuration of all elements, though it is not possible to list all of them here.
The noble gas configuration for zinc is [Ar] 3d10 4s2. This means that zinc has the same electron configuration as the noble gas argon, and then has two more electrons in the 4s orbital.
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, 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.
The noble gas configuration of O2 is similar to that of neon (Ne). Oxygen (O) typically forms a stable configuration by gaining 2 electrons to achieve a full valence shell, similar to the configuration of a noble gas.
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.
