The non-metals or non-metallic elements; hydrogen (H), carbon (C), nitrogen (N), oxygen (O), phosphorus (P), sulphur (sulfer) (S), selenium (Se), (Uuo may belong here) and the noble gases form a relatively small group with a step like pattern towards the left-hand side of the periodic table (hydrogen being the odd one
Similarly, you may ask, is nitrogen a molecule or compound?
Nitrogen itself is an element. But nitrogen is found as N2 in nature. A compound is a molecule that contains at least two different elements (i.e. water) while a molecule is formed when two or more atoms join chemically. All compounds are molecules but not all molecules are compounds.
How big is a molecule of nitrogen?
Well, a nitrogen molecule measures roughly 300 picometers while an oxygen molecule measures 292 picometers. That's only a 2.6% difference in size. One picometer is equal to one trillionth of a meter (1 m / 1,000,000,000,000).
