How many electrons are called are needed in the outer energy level of most atoms for the atom to be stable?

Most atoms are stable when they have a full outer energy level, which typically consists of 8 electrons. This is known as the octet rule. However, some smaller atoms, such as hydrogen and helium, are stable with only 2 electrons in their outer energy level.


Which atom does not need 8 electrons in it outer energy level to be stable?

Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.

How many valence electrons in fluorine are needed to have a filled outer energy level?

Fluorine needs 8 valence electrons to have a filled outer energy level, following the octet rule. Fluorine naturally has 7 valence electrons, so it only requires one more electron to achieve a stable octet configuration.


How many electrons are needed to fill the second outer energy level?

8 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.
