When writing fiction, there are no rules, other than those that you create for yourself. (James Joyce, for example, decided to omit nearly all punctuation in Ulysses. It was neither 'right' nor 'wrong'; it was just the way that he thought the book would work best).
Many novels don't even have separate chapters, whereas others are divided into many chapters (with the author ending one chapter, and starting another, wherever a break in the story seems natural to him/her).
My own preference is to end a chapter at a point where the work has reached a natural 'cliff-hanger' - but that might just be because I watched too many serials at the Saturday morning pictures when I was a kid!
