8 electrons is the correct answer, but helium has 2 if you needed to know that.

certain it really is yet helium is the in person-friendly words exception (it does no longer have 8 electrons, it has 2) the reason why its a noble gasoline is because it doesnt react with different factors really it really is because it has an entire valence shell of electrons (all noble gases have an entire valence shell) its in simple terms that helium is sufficiently small to have in simple terms the 1s orbital filled, and in person-friendly words the 1s orbital
