WebNitrogen is a chemical element with atomic number 7 which means there are 7 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. WebAlex Bolano. Nitrogen Dioxide (NO 2) is a covalent compound that is composed of a central nitrogen atom single bonded to an oxygen atom and a double bond with another oxygen atom. At room temperatures, nitrogen dioxide is a reddish-brown gas that has a density of 1.8 g/dm 3. It is slightly toxic to humans, on account of its tendency to react in ...
