identify and describe layer a in the figure above

Layer A is the thermosphere. In the thermosphere, atoms of nitrogen and oxygen absorb solar radiation (sunlight), which is converted to heat. The temperature of the thermosphere is incredibly high due to the radiation absorbed by each molecule. However, because the molecules that make up the thermosphere are so spread out, heat is not easily transferred from molecule to molecule. Therefore, there is not much heat retained in the thermosphere.

Explanation:

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
