When two nitrogen atoms bond-they share three pairs of valence electrons. Why does this happen?

It happens so that each nitrogen atom can have 8 electrons (an octet), which is a stable form. It results in a nitrogen triple bonded to another nitrogen, and then each nitrogen has a lone pair of electrons. :N triple bond N:

When two nitrogen atoms bond they share three pairs of valence why does this happen?
Nitrogen's position on the periodic table means it is 3 electrons short of the stable noble gas configuration on Neon. If two Nitrogen atoms mutually share 3 electrons to form a triple bond, each nitrogen will have its required quota of electrons to iso-electronic with Neon and thus be stable.
What happen to carbon atoms valence electrons when it bonds with other atoms?
Atoms gain lose or share valence electrons in a way that makes the atoms more stable
What two posibilities happen to valence electrons when a chemical bond is formed?
They can either be shared (covalent bond) or transferred (ionic bond)
What happens to the valence electrons when new compounds are formed?
This is a somewhat broad question because there are many different kinds of compounds, and there are a variety of things that happen to valence electrons depending upon what kind of compound is formed, but in general, any given atom has 3 options when forming a compound: it can give up one or more electrons, acquire one or more electrons, or share one or more electrons.
What do you notice about the valance electrons as you move down a group?
stays the same Well... that's not really true... the number of them stays the same, but several things happen to them. First off they are further from the nucleus. And they are further shielded by additional electrons between the valence and nucleus. This causes a looser association and tends to make the atom more volatile.

What is Nitrogen's valence electron configuration?
When answering these questions just refer to the periodic table. Nitrogen is in the 5th column (excluding the d block) This means that Nitrogen has 5 valence or outer electrons (free electrons) I am assuming that you are referring to N2. NOTE we always want to achieve the stable 8 electron configuration but this cannot always happen. In the case of N2 this is possible since we have 2 N's therefore we have 2 x 5 electrons=10 we can have single double and triple bonds. single has 2 electrons double has 4 electrons triple has three therefore for each N to have 8 electrons (the stable number) :N(three lines)N: hence 2x2+3x2=10 so we are right this is the electron configuration.
When 2 nitrogen atom bond they share 3 pair of valance electrons why does this happen?
Nitrogen's position on the periodic table means it is 3 electrons short of the stable noble gas configuration on Neon. If two Nitrogen atoms mutually share 3 electrons to form a triple bond, each nitrogen will have its required quota of electrons to iso-electronic with Neon and thus be stable. Add: Nitrogen atoms have five valence electrons. Two of the valence electrons form a lone pair, and the other three electrons are unpaired. Nitrogen atoms bond with one another by each sharing its three unpaired electrons with the other. This gives each of them six paired electrons, plus the two lone pairs of electrons on each nitrogen atom, which all together forms an octet for each nitrogen atom. An octet is a noble gas configuration, which makes the N2 molecule stable. The lewis dot diagram for an N2 molecule is :N:::N: .
When metals react with other elements what happen to the valence electrons of the metals atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
What happen to carbon atoms valence electrons when it bonds with other atoms?
Atoms gain lose or share valence electrons in a way that makes the atoms more stable
What must happen to a calcium atom for it to achieve noble gas structure?
It must give away two valence electrons.
Can the sharing of electrons only happen on the outer most energy level of the atom?
Yes, bonds and reactions are caused by the valence electrons only (the outermost principle energy level).
What two posibilities happen to valence electrons when a chemical bond is formed?
They can either be shared (covalent bond) or transferred (ionic bond)

What are the two possibilities that will happen to a valence electron during bonding?
During ionic bonding, the valence electrons are either lost or gained, depending on which group the element is. eg. Na + Cl --> Na+ + Cl- Na has lost an valence electron and Cl has gained an that electron. During covalent bonding, the valence electrons are shared between two atoms. eg. 2H2 + O2 --> 2H2O In H2O, each Hydrogen atom shares one pair of electrons with Oxygen by forming a covalent bond.
