Why does sulfur have a valency of 4 and 6 when it needs only 2 electrons for stable configuration?
It has 6 electrons in it's valance shell and needs 2 more electrons in it's valance shell to become stable. Some atoms, phosphorous for instance ( valance # 5 ), can reach deeper into their valance shell and make additional covalent bonds.
How many valance electrons in neon?
Eight - it has a full outer shell of electrons.
When a valance shell has 7 electrons will it gain or lose an electron?
It will gain an electron so that it can complete a full outer shell of 8 electrons.
What is unreactive and has a full shell on the periodic table?
A noble gas is usually unreactive and has a filled valance electron shell. They are located in group 18 on the periodic table.
How many valance electrons are found in an atom what elements Neon?
there are 8 electrons in the valence shell of neon
What valance shell does hydrogen belong to?
K shell.
What makes a group not reactive on the periodic table?
A full octet, valance shell. A valance shell with eight electrons, such as the Nobel gases have, doe not need to donate or accept electrons into or out of the valance shell to be stable.
How many additional valance electrons does fluorine need to have a valance shell?
1
Is the valance shell innermost or outtermost?
outermost
What does a valence shell have to do with chemical reactions?
The valance shell is important in chemical reactions, as it is the valance electrons which are gained/lost during reactions. An atoms valance electron configuration is what largely determines its chemical reactivity.
What is on the outer part of the atom?
"valance shell"

Why is Zn not anoble gas?
It's valance shell does not contain an octet of eight valance electrons. That simple.
How are valence electrons related to stability?
8 valance electrons in valance shell means that atom is stable.
Complete valance shell holds electrons?
8
How many electrons does the valance shell in hydrogen have?
1
How many atoms in the valence shell of sodium?
There is one electron in sodium's valance shell.
