∙ 11y agoNone. Neon is a noble gas, a category of elements that exist in nature as inert gasses. In special situations, neon can be made to react with other elements, but in ordinary conditions, neon is inert, which just means non-reactive. It's outer orbit is full--it doesn't want to give up the electrons it has, or to take any more.

∙ 15y agoOxygen is in group 16 so it has 6 valence electrons. In order to have a full outer shell, and satisfy the octet rule, it needs 2 more valence electrons to have a full outer shell.

∙ 12y agoNone: Noble gases are noble because they have a full outer valence shell.

Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.

The reactivity of elements is related to the number of valence electrons in atoms. Elements with few valence electrons tend to be more reactive because they are more likely to gain or lose electrons to achieve a stable electron configuration. Elements with full outer electron shells are typically stable and less reactive.
Nitrogen has 7 electrons, oxygen has 8 electrons, and chlorine has 9 electrons. That is the total electron count, for inner and outer shells. If you are only concerned with the valance electrons, then it is 5 for nitrogen, 6 for oxygen, and 7 for chlorine.
6 valence electrons 1s2 2s2 2p4 These 6 valence electrons are in the outer shell.
Valance electrons
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
There are three valance electrons. These are the electrons in the outer shell if it is not full.
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
Neon has more valence electrons than oxygen. Neon has a full outer shell with 8 valence electrons, while oxygen typically has 6 valence electrons.
3 valence electronsThere are three valance electrons. These are the electrons in the outer shell if it is not full.
Oxygen has 6 electrons in its outer shell. It belongs to group 16 of the periodic table, also known as the oxygen family or chalcogens, and has 6 valence electrons.
The valence number of krypton is 8. This means that krypton has 8 valence electrons in its outer shell.
Valence electrons are the outermost electrons in an atom. They are located in the outer energy levels or orbitals, specifically in the highest principal energy level. These valence electrons are involved in chemical bonding and determining the atom's reactivity.
Magnesium has 2 electrons in its outer most shell and these 2 are the valency electrons.
The valance electrons. The outer level of electrons every atom has. Every atom has a full valance shell at 8, so only the Nobel gasses are nonreactive naturally and other atoms either donate or accept the number of electrons needed to come to an octet of electrons.
