Helium only needs two electrons to have a filled outermost energy level.


Helium atoms only need how many valence electrons to have a filled outermost energy level?

Helium atoms only need 2 valence electrons to have a filled outermost energy level because helium is in the first period of the periodic table and its outermost energy level can only hold a maximum of 2 electrons.


A helium he atom has 2 electrons that are both in the outermost energy level how many more electrons does the atom need to fill its outermost energy level?

It is the most stable element in the universe and does not need anymore electrons. Its outermost energy level is full.


How many electrons can be found in the outermost shell helium?

2 electrons in the only shell helium has.


How many electrons are in the outermost shell of helium?

only 2 electrons.


How many valence electrons does helium need to gain to have a filled outermost energy level?

0 It already is full


How many electrons are in the second energy level of helium?

Helium has two electrons total, and the second energy level can hold a maximum of 8 electrons. However, in the case of helium, the second energy level will only contain two electrons as it is the outermost energy level.


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.


How many number of electrons of helium in outer ring?

Helium has only two electrons with one ring (or energy level). Both the electrons are in the one and only energy level / shell / ring.


How many electrons are found in the outer lever of all the noble gases except helium?

There are 8 electrons in the outer level of all the noble gases except helium. This full outer level gives them stability and makes them less reactive. Helium, as a noble gas, has only 2 electrons in its outer level.


How many electrons are in the outermost level of carbon?

Carbon has 4 outermost electrons.


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.
