Hi, and welcome

Generally speaking, there is no real rule that you can memorize. That is, there is no pattern that tells you whether an antonym can be formed with im-, un-, in-, etc.

Sometimes there seems to be a pattern...

impossible
improbable
impatient


but then comes

paid >> unpaid

and spoils it

Overall, you just have to memorize them "as they are".
