how many valence electrons are found in most atoms of the noble gas?

Answer 1

There is no one "noble gas". Instead, the noble gases are all the elements found on group 18 of the periodic table. In order of increasing atomic mass (going down the periodic table) these are Helium, Neon, Argon, Krypton, Xenon, and Radon.

Each noble gas atom* has a full outer shell of 8 valence electrons. This is the reason they are very nonreactive- they are 'happy' with the electrons they have; they want no more and no less.

*With the exception of Helium which only has two electrons (which are both in its valence, or outer shell).

Answer 2

seem on the Periodic table of components. The Atomic selection tells you techniques many electrons are in the atom. The electrons are in 'Orbit' around the Nucleus (The Protons and Neutrons that make up the Atomic Mass selection). The electrons are contained in 'potential Shells' and each shell has a maxinmum style of electrons. that's the Outer shell that holds the Valence Electrons. additionally in the Periodic table, each and every element has that's Atomic selection (style of Protons (& if that's a physically powerful element, the comparable style of electrons). there is likewise a selection a million, 2, 3, 4... etc. that's the style of Valence electrons of the element listed. from time to time, there are numbers like.. 2,3, or 3,6 etc.. meaning that the element has as much as 3 or 6 valence electrons ..etc, obtainable.

Answer 3

noble atoms are inert gases.and all they do not forn any bonds with any oder atoms.Helium being the lowest in the group has 2 valence electrons..Others Startin from Neon have 8 valence electrons in their outermost shell.

Answer 4

He has two since there is only the s orbital available to He. Ne, Ar, Kr all have eight valence electrons. Since they have eight valence electrons, their octets are full, thus they ar virtually non-reactive.

Answer 5

scince their last shell is complite they have no valance electrons.

Answer 6

0 is the answer.
