Helium is already full.
Helium atoms only need 2 electrons to be full, and Helium, as an element, already has 2.

How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs 2 valence electrons to have a filled outermost energy level.
What are valence electrons and how do they relate to the noble gases?
Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.
How many electrons are in the outermost energy level of noble gases?
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
Are the valence electrons the outermost electrons?
Yes. Valence electrons are the electrons found in the outermost shell / energy level
How many valence electrons does helium need to gain to have a filled outermost energy level?
0 It already is full

What contains 8 electrons in the outermost energy level?
Noble gases (except for helium which has 2 valence electrons).
How many electrons are in the outermost energy level of noble gases?

Are the valence electrons the outermost electrons?
Yes. Valence electrons are the electrons found in the outermost shell / energy level
How many valence electrons does helium need to have filled outermost energy level?
helium has 2 valence electrons (in s orbital) and has complete s orbital. So it does not need to gain or lose more electrons to be stable.
Why is a helium atom stable with only two electrons in its outermost energy level?
helium has completely filled valence orbitals and hence is stable
An electron in the outermost energy level of an atom is a?
The outermost electrons are called VALENCE electrons.
How many valence electrons does helium need to gain to have a filled outermost energy level?
0 It already is full
Which electron in an atom are the valence electrons?
The valence electrons are the outermost electrons, i.e. those that reside in the outermost energy level.
What is the word for the definition electrons in the outermost energy level of an atom?
valence electrons are the electrons in the outermost energy level
Valence electron are found in what energy level?
Valence electrons are the electrons in the outermost energy level.
