How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs two electrons to have a filled outermost energy level.
Which element has a full outermost energy level contining only two electrons?
Helium has a full outermost energy level containing only two 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.
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.
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)
Which noble gas does not have eight electrons in it's highest occupied energy level?
Helium is the noble gas that does not have eight electrons in its highest occupied energy level. It only has two electrons in its outermost energy level.
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 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.
Which element has a full outermost energy level with 2 electrons?
All of them. The s1 shell is the outermost electron shell. Despite being the first shell quoted and the lowest in energy, it is actually the largest in average diameter, and so is the "outermost."
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).
