If a compound contains an even number of nitrogen atoms (or no nitrogen atoms), its molecular ion will appear at an even mass number. If, however, a compound contains an odd number of nitrogen atoms, then its molecular ion will appear at an odd mass value. This rule is very useful for determining the nitrogen content of an unknown compound.
As a rule of thumb, the atomic mass of an element equals the number of grams of that element equals a mole. Since the atomic mass of Nitrogen is 14, there are 14 grams in one mole of Nitrogen. Next, we just have to divide 42 by 14 and we get our answer: There are 2.9988 moles in 42 grams of Nitrogen.
Nitrogen and oxygen can share electrons in many different ways; some observing the octet rule and some not. For this reason, prefixes are necessary to keep track of all the covalent combinations.
nitrogen is N
The length of nitrogen-to-nitrogen bond is approx. 100 pm.
2. Nitrogen in the atmosphere here on Earth is considered diatomic.
NH3 is not an exception to the octet rule. Nitrogen (N) in NH3 has a total of 8 valence electrons (5 from nitrogen and 3 from hydrogen), fulfilling the octet rule. Nitrogen has 3 bonded pairs and 1 lone pair of electrons, following the octet rule.
Of course it does obey.There are 8 electrons around Nitrogen.
Nitrogen dioxide (NO2) violates the octet rule because nitrogen has one unpaired electron, giving it a total of 7 valence electrons in its outer shell. This results in NO2 having an odd number of electrons, making it impossible for nitrogen to achieve a full octet.

Nitrogen can gain three electrons to form an ion with a charge of -3. This would give nitrogen a stable octet of electrons in its outer shell, following the octet rule.
In regards to fertilizing, the rule is a reminder that nitrogen helps green the grass, phosphorous helps the root systems, and potassium helps the whole plant.

HNNHThe first compound(H2NNH2) has a single bong between the nitrogen atoms and follows the octet rule allowing nitrogen's orbital to hold 8 electrons. The second compound (HNNH) requires nitrogen to be double bonded. Double bonds are stronger than single bonds.Source:Yahoo Answers

As a general rule, liquids don't freeze things. But the gas, Liquid Nitrogen, can freeze things.
Nitrogen has five valence electrons as a neutral atom, but it is shooting for eight. So it needs to gain three more electrons.
