In the reaction of sodium metal with chlorine gas to form sodium chloride, how does chlorine form an anion? Write an equation to support your answer.

I know that chlorine becomes an anion since it's gaining an electron from sodium, but how do I show that in an equation?

1 answer

Yes, Cl atom forms an anion by adding an electron. Cl + e ==> Cl^- or if you want the entire equation it is
2Na + Cl2 ==> 2Na^+ + 2Cl^-
