Why do group one elements have similar properties?
;need the same number of electrons to fill their valece shells ;have the same number of 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 the number of valence elecrtons in N?
5
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.
How many valence shells in radium?
Radium has seven electron shells; the valence of radium is 2+.
Why do group one elements have similar properties?

How many valence shells in beryllium?
Beryllium has one valence shell containing two electrons.
How many valence shells does fluorine have?
flurine has atomic no. 9 so its electronic configaration is 2,7. Its valance shell has 7 electrons

Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
How many valence shells does an atom has?
The valence shell is the outermost shell...and an atom can only have one outer shell.
