The greatest concentration of nitrogen on the planet earth is found in

Nitrogen is one of the most fundamental and vital source of energy on the planet Earth, as there are a number of places where the element is found in fractional forms. The atmosphere when analyzed by the research workers and other professional was attributed to have about 3/4th of nitrogen molecules inside its basic composition.As the density of nitrogen is more in air or we can say in the atmosphere then any where else on planet Earth.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
