Lol in my research paper, I said that chlorine is found primarily as a cation. LOl.

Chlorine is not found primarily as a cation. I don't think it's ever even found as a cation. Chlorine is always found as an anion. Why? Chlorine is a halogen. The halogens are group 7A. They all have 7 valence electrons. Since the halogens follow the octet rule as do pretty much all the other elements, the halogens are always trying to gain one more electron, in order to get 8 valence electrons. The halogens are all extremely good at this. They are almost never found simply as a pure element. But what does adding an extra electron do? Electrons have a negative charge, thus making the atom an ion. The charges in the atom do not balance out, because of the extra negative. This leads to the atom having an overall negative charge. There are two kinds of ions: cations and anions. A cation is an ion with a positive charge. An anion is an ion with a negative charge.
Therefore chlorine ions are obviously anions, not cations.

Wow there are people in lower divisions of Mathfights with pretty high ratings.
And this is kinda stupid:
I was like 1100-something, and I beat someone who was 1800-something. I gained like 20 or something.
Someone else who's like 1400-something beats me and gains like 50.
