If the moon did not rotate we would see all hemispheres of the moon as it revolves around the Earth and not just the phases.
The answer for this question is: Atoms
Answer:
d) An atom of arsenic has one more valence electron and more electron shells than an atom of silicon, so the conductivity increases because the arsenic atom loses the electron.
Explanation:
This is an example of a n-type semiconductor. The additional electron introduced to the 'grid' of silicon atoms causes an increase in the conductivity of the silicon. This additional electron is introduced as arsenic loses its extra electron.
D, since it can hold up to 10 electrons
