helium has only 2 electrons and hence its configuration is 1s2
gas
Yes it does. Helium has 2 electrons in the s orbital. A s orbital can hold a maximum of two electrons.
Helium has a full outer shell of electrons and so is more like the other noble gasses than the other, much more reactive s-orbital elements. With the exception of hydrogen and helium all of the s-orbital elements are metals.

Helium is a noble gas with an atomic number of 2, meaning it has 2 protons in its nucleus. This atomicity indicates that each helium atom has a single electron cloud surrounding its nucleus. Helium typically exists as a monatomic gas under standard conditions.
This isotope of helium is helium-3; the atomic number of helium is 2.
helium`s charge is H+, is a positive charge

The heaviest element whose atoms ave more s electrons than p electrons is helium. Helium is found in a wide variety of compounds, including water of H20, for instance.
