What is the number of pairs of electrons that are shared between the nitrogen atoms in a molecule of N2?
Elemental nitrogen has 7 electrons.
Thus, the first (or K) shell of electrons contains 2 of them (the maximum that the K shell can accommodate).
The second (or L) shell of electrons contains the remaining 5, however, the maximum number of electrons that the L shell can accommodate is 8.
Therefore, elemental nitrogen has three unpaired electrons that can be used to form covalent bonds.
In ammonia (NH3) all three of those unpaired electrons are paired with hydrogen atoms.
Leaving only a single unshared pair of electrons in the L shell.
Technically, the pair of electrons in the K shell are also an "unshared" pair but they are unavailable for covalent activity so are generally not considered as such.

What is the total number of electrons that must be represented by the Lewis structure of a hydrogen cyanide molecule HCN?
The total number of electrons in a hydrogen cyanide (HCN) molecule is 10. Hydrogen contributes 2 electrons, carbon contributes 4 electrons, and nitrogen contributes 5 electrons. Combined, this totals 11 electrons.
Why N2 is a molecule of an element?
N2 is a molecules of an element because both atoms in the molecule have the same number of protons (7). A lone nitrogen atom is somewhat unstable as it needs 3 more valence electrons for a full outer shell. To fill this shell it shares electrons with another nitrogen atom.
The number of electrons in one molecule of CO?
There are 22 electrons in one molecule of CO2.
What are the number of valence elecrtons in N?
5
Will nitrogen gain number of electrons gained or lost?
Gaining electrons lead to decrease in oxidation state.
How many bonding electrons in a nitrogen molecule?
there are 5 bonding electrons. It depends on the number of valence electrons.
What is the number of valence electrons in a nitrogen molecule?
A nitrogen molecule, N2, has a total of 10 valence electrons. Each nitrogen atom contributes 5 valence electrons.
What is the total number of electrons in nitrogen?
The Nitrogen Atom possesses seven protons in its nucleus; therefore the electrically neutral atom of Nitrogen has seven electrons in orbit about it.
What is the number of valence electrons in a molecule of ammonia?
A molecule of ammonia (NH3) has 8 valence electrons - 5 from nitrogen and 1 each from the three hydrogen atoms.
What is the number of shared pairs of electrons in a molecule of NH3?
There are three bonds between Nitrogen and hydrogen and there are thus 3 shared bonding pairs of electrons. in addition since Nitrogen is 1s22s22p3 there are also the none bonding 1s2 electrons and the 2s2 electrons making 5 total shared pairs of electrons.

How many core electrons in nitrogen?
Nitrogen has 2 core electrons and 5 valence electrons. If you remember, nitrogen has an atomic number of 7. When an atom is neutral it has an equal number of protons and electrons. Therfore, the overal number of electrons is 7. The definition of core electrons is, electrons in their most inner shell, On the other hand valence electrons are electrons in the outermostshell. When looking at a periodic table you see that there is a total# of 5 valence electrons. In order to figure out the core number you subtract the total number of electrons(atomic #) - Valence # of electrons. I hope this helped :)
How many bonding and non-bonding electrons does nitrogen have?
In order to have a net charge of zero, nitrogen can have three bonds. it will often have more or less than that number with a charge on the atom. Example: Ammonia (NH3) versus Ammonium (NH4+)
Why is the bond order for Nitrogen ion lower than the bond order for nitrogen atom?
The negativelly charged molecule would involve addition of electrons to anti-bonding orbitals so reducing bond order. The poitivelly charged molecule would involve the loss of electrons in bonding orbials again giving a reduction of bond order.
The number of electrons in one molecule of CO?
There are 22 electrons in one molecule of CO2.
Number of covalent bonds in nitrogen?
Covalent bonds do not "make up" anything; they merely hold the atoms that carry the mass of the substance together. If the questioner means, "How many covalent bonds are in a nitrogen molecule with formula N2" the answer is "one triple covalent bond."
