Roughly, Aufbau Principle says that in an atom or an ion, electrons enter the shell with low energy first before entering the shell with high energy.
An atom has shells around its nucleus. Electrons enter these shells and orbit around the nucleus of an atom. To say about the properties of these shells, the shell nearest to the nucleus has the lowest energy. The farther the shell from the nucleus, the higher its energy. Aufbau Principle states that electrons enter the closest shell to the nucleus first since it has the lowest energy. When that shell has its maximum number of electrons is can hold, then the next electron will enter the second-closest shell to the nucleus, which has higher energy than the first shell.
A) because you are moving closer to the moon
Hey there!
Let's remember something. All over us, there is pressure, everywhere we go. So, this means that, if you were to hold something, (especially) high off the ground and there is higher pressure in the sky then on level ground, this would mean that the molecules would be more complex, and they would break down.
So, from your options listed above, I believe that the best answer to would go with this question would be Option B.) <span>They break down complex molecules.
I hope this helps you!
