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.
Does helium has a full outermost energy level with two electrons?
Yes it does.
What atom has a full outermost energy level that contains two electrons?
helium
Which element has a full outermost energy level containing two electrons?
Helium (He)
What element could have two electrons in their outermost level and be full?
Helium has only 2 electrons and its energy level is full.
How many electrons are in outermost level of helium?
Helium has 2 valence electrons.
What contains 8 electrons in the outermost energy level?
Noble gases (except for helium which has 2 valence electrons).
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
How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
What are seven electrons in the outermost energy level?
Halogens have six valence electrons in the 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.
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
