You can leave and rejoin any room in Google Chat. If you leave a room, you won't get room updates or be able to post messages unless you rejoin.
If you rejoin a room, you can view all the message history, including the messages that you missed. If you're removed from a room by someone else, you must be re-invited before you can rejoin.
