it can form 3 bonds because 1 electron is in each of the 3 2p oribitals.
The electron configuration of nitrogen (atomic number 7) is 1s2 2s2 2px1 2py1 2pz1
so specifically the 2p oribital is :
2px1 2py1 2pz1
The valence part is referring to the outer most ring of electrons. Carbon only has four on the 'valence' or outer most ring helping it to form bonds with other things. I hope this helps!! Good Luck!!! :)
Answer:
as you move away from a planet the gravitational force gets weaker. just think, if you get close towards a sun then the gravitational force will be stronger.
Answer:
From the atmosphere to the hydrosphere by diffusion.
From the atmosphere to the biosphere by photosynthesis.
From the atmosphere to the geosphere by rainfall.
Explanation:
Carbon atom goes from the atmosphere to the hydrosphere by the process of diffusion because there is high concentration of carbondioxide present in the atmosphere. The carbon atom goes from the atmosphere to the biosphere by the process of photosynthesis in plants which uses carbondioxide gas as a raw material in the process for the preparation of organic compounds such as glucose. The carbon atom goes from the atmosphere to the geosphere with the help of rain. When carbondioxide gas react with water in the atmosphere, carbonic acid is formed and comes to the ground through rainfall.
