Answer:
11 protons, 11 electrons, 12 neutrons
Explanation:
Protons are equal to the atomic number, so 11 in this case. Electrons are equivalent to Protons if the atom is not an ion. Electrons are 11 as well. To find Neutrons, you subtract the atomic number from the mass, which would mean that there are 12 Neurons.

Answer:
Nitrogen is present in the atmosphere in a molecule form about 78 percent. This nitrogen comes to the earth with the water through rainfall. Some nitrogen fix by beneficial microorganisms such as Cyanobacteria and Azotobactor which are present in the roots of higher plants. These microorganisms convert nitrogen molecule into nitrates and used by the plants. There are some other microorganisms which again convert nitrate into nitrogen molecules, called denitrifying bacteria and nitrogen molecule goes to the atmosphere again and complete the cycle.
