Why does nitrogen have three covalent bonds?

Answer 1

Nitrogen's atomic number is 7, which means it's got two orbitals. The inner one has two electrons in it, like every atom except hydrogen has. The outer orbital has five electrons. An orbital can have as many as eight electrons. It can get them either from itself or by sharing with other atoms. So...it has five electrons of its own, shares three with three hydrogen atoms, and makes a stable compound.

Answer 2

the num of bonding electrons is eight while number of anti bonding electrons is 2.we know that the bond order of any molecule is num of bonding electrons minus number of anti bonding electrons divided by two.so,8-2/2=3,thats why bond order of nitrogen molecule is 3.

Answer 3

Nitrogen has three electrons missing (5 valence electrons) to get to the stable Neon configuration. The molecule N2 thus shares 3 pairs of electrons (a triple covalent bond) so that each N atom has the required 8 outer electrons to be like Neon.

Answer 4

They have to share 3 pairs of electrons, because then each nitrogen atom can have a total of 8. The "octet rule," or rule of 8 says that atoms want to have 8 electrons in their outer, or valence shell. This mimics the electron configuration of noble gases (group 18) which are very stable. Nitrogen is one of 7 diatomic elements, which always exist as a diatomic (2-atom) molecule, and the only way for each nitrogen atom to be stable is for the 2 nitrogen atoms to share 3 pairs, forming a triple covalent bond.

Answer 5

Because it has 3 unpaired electrons in it outershell so can form 3 covalent bonds, sharing 1 electron in each bond.

Answer 6

NH3 is ammonia or azane, a gas that is highly soluble in water (creating NH4OH an alkali).

Answer 7

The molecular formula of ammonia is NH3. According to the formula, the ratio of nitrogen to hydrogen is 1N:3H.

Answer 8

Ammonia, NH3.
