O valence electron number is the answer
Answer:
The correct answer is cation. See the explanation below, please.
Explanation:
An atom with a net charge, either positive or negative, is called an ion. In the event that an atom loses an electron (or more), that is, it will have more protons than electrons, and its net charge will be positive, it will be called cation. In the opposite direction, if an atom gains electrons, it will have a negative net charge, called anion.
I would say D. Let me know if i am wrong.
B, I would believe. There are 58, but B is the closest we can get.
It should be <em>Ultraviolet rays </em>because they are moderate in energy.
