The Noble Gases are so-called because they do not readily react chemically with anything, due to their valence electron shells being filled with 8 electrons.
The exception, of course, is helium, He, which only has 2.
Helium has 2 valence electrons; all other noble gases have 8 valence electrons.
none, that is why they don't react.
Only valence electrons.
They are the electrons in the outermost shell, and are the ones involved in most chemical reactions.
Yes. Valence electrons are the electrons found in the outermost shell / energy level
Mg has 2 valence electrons.
Valence electrons are the electrons in the outermost energy level.
Valence Electrons
Only valence electrons.
Valence electrons
The electrons in the outermost shell is called as valence electron. These electrons are free and they are involved in bonding reactions.
I suspect the term you're looking for is "valence electrons."
A neutral atom of silicon will have 4 valence electrons. The amount of valence electrons that a neutral atom will have can be found by the atoms group number in the periodic table.
Valence electrons are: In chemistry, those electrons found in orbits farthest from the nucleus of the atom. These electrons determine the way in which the atom will combine with other atoms, and thus determine its chemical properties.

The electrons in the atom are found on the outer rings, the limit of 2 on the first up to 8 on the valence ring. The number of the electrons found on the valence ring determines where the chemical is placed on the Periodic Table.
Valence electron are found in the outer shell of an atom. Depending on the number of valence electrons, the atom is more or less stable: fewer => less stable and more => more stable (inert). Stable = less likely to react with other atoms.

There are only 2 valence electron found in calcium.
