Question

How can you predict if an element will form a cation or an anion?

Answer 1

By the number of electrons it would have to gain or lose to get to noble gas electron configuration.

Answer 2

For example, F only needs one more electron to get to 8 valence electrons, but it would ned to lose 7. Gaining one is much easier than losing 7.
