How many sea scallops for one person?

I'm curious, when it comes to preparing a seafood dish featuring sea scallops, what would be the recommended serving size for a single person? Is there a standard quantity that chefs often follow to ensure each diner receives an optimal portion, or does it vary based on the size of the scallops and the rest of the meal? I'm looking to create a memorable dining experience and want to make sure I'm getting it just right.
