<u>Answer:</u> The average atomic mass of the element is 6.95 amu
<u>Explanation:</u>
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
.....(1)
We are given:
Mass of isotope 1 = 7.02 amu
Percentage abundance of isotope 1 = 92.6 %
Fractional abundance of isotope 1 = 0.926
Mass of isotope 2 = 6.02 amu
Percentage abundance of isotope 2 = 7.42 %
Fractional abundance of isotope 2 = 0.0742
Putting values in equation 1, we get:
![\text{Average atomic mass of element}=[(7.02\times 0.926)+(6.02\times 0.0742)]](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20atomic%20mass%20of%20element%7D%3D%5B%287.02%5Ctimes%200.926%29%2B%286.02%5Ctimes%200.0742%29%5D)
Hence, the average atomic mass of the element is 6.95 amu
The process in the nitrogen cycle converts nitrogen into its most polluting form will be "nitrification".
The biological process of nitrification turns ammonia into nitrite and nitrite into nitrate. The technique of denitrification, which turns nitrate into nitrogen gas, is such treatment option if requirements demand that the resultant nitrate be eliminated.
A surplus of nitrogen compounds could result in pollutants like ammonia and ozone that can affect plant growth, visibility, and human capacity to breathe. Excess nitrogen from the atmosphere that returns to earth could be damaging to the health of forests, soils, including streams.
Therefore, the process in the nitrogen cycle converts nitrogen into its most polluting form will be "nitrification".

N has a lone pair... the lone pair-bond pair repulsion is greater than the bond pair-bond pair repulsion so the tetrahedral geometry of N will be distorted.
