What is the value of n for the valence shells of as?
The value of 'n' for the valence shells is the number of shells that specific atom has
Does carbon have three electrons in its valence shells yes or no?
No, carbon has 4 valence electrons.
How many valence shells does the element neon have?
Period number = no. of electron shells. Therefore neon has two shells.
Why are noble gases are non reactive?
They have filled valence shells. Atoms undergo chemical bonding in order to have filled valence shells by sharing electrons or transferring electrons. Because the noble gases already have filled valence shells, they have no need to react with other elements.
What are valence electrons and shells?
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are valence electrons).
Do noble gases have valence shells?
Yes they have eight electrons in their valence shells. This is why they are not reactive. All elements have valence shells.
What is the value of n for the valence shells of as?
The value of 'n' for the valence shells is the number of shells that specific atom has
How many valence shells in radium?
Radium has seven electron shells; the valence of radium is 2+.
Can nonmetals gain electrons to fill their valence shells?
Yes, nonmetals generally gain electrons to fill valence shells.
How many valence shells does chlorine have?
3
Does carbon have three electrons in its valence shells yes or no?

How many valence shells does the element neon have?
Period number = no. of electron shells. Therefore neon has two shells.
How many valence shells in beryllium?
Beryllium has one valence shell containing two electrons.
As you move across a period elements have the same number of?
Electron shells
Why are noble gases are non reactive?
They have filled valence shells. Atoms undergo chemical bonding in order to have filled valence shells by sharing electrons or transferring electrons. Because the noble gases already have filled valence shells, they have no need to react with other elements.
How many electrons are in the valence shell of francium?
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
