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.
None. 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.
No. Helium is a completley inert gas and is not known to undergo ANY chemical reactions.
Nitrogen is a poor conductor of electricity because it is a nonmetal with a full valence shell of electrons, making it difficult for electrons to move freely through the material. Therefore, nitrogen gas is an insulator and does not readily conduct electricity.
Calcium would need to lose 2 electrons to have 8 valence electrons. This is because calcium has 2 valence electrons in its outer shell, and by losing these 2 electrons, it can achieve a stable octet configuration like the noble gas argon.
Helium is a noble gas with 2 valence electrons.
Krypton is an inert gas.
Krypton has 8 valence electrons that is 4s2 4p6.it is chemically inert since it attains an octet configuration.
Noble gases (such as neon) have full valence electron shells (8 electrons).
Helium is the only noble gas that doesn't have 8 valence electrons. It only has 2.
Argon is a noble gas with a full valence shell of electrons, so it does not typically gain or lose electrons. It is considered chemically inert due to its stable electron configuration.
Xenon is a nonmetal. It is a noble gas located in group 18 of the periodic table. It is known for being inert and having a full valence shell of electrons, making it stable and nonreactive.
NONE!!!! There are 8 electrons in its outer energy shell. This completes its electron OCTET, thereby making it unreactive. Valence electrons are those which take part in combining the atom with another atom. Since Xenon is a Noble(Inert) gas it does not react with anything, thereby there are no valence electrons.
A full outer electron shell, the so-called valence shell, creates an inert gas in those elements (the inert or noble gases). In other elements, what is called "inert gas configuration" will apear in the Halogens (the Group 17 elements) and some Group 16 elements. When they "borrow" an electron or electrons in an ionic bond, they do so to achieve "inert gas configuration" by "filling" their valence shell with the borrowed electrons.
any atom that has or acquires a valence shell containing exactly eight electrons often is or becomes quite inert.
Helium has 8 valence electrons. It is a noble gas. none = 0
Yes, because it has a complete valence orbit.
