Why is NH3 sometimes written as H3N?

They both mean the same thing.

You might see H3N written if it is trying to be conveyed that the N is what is attached to the next atom instead of the H.

For instance: H3NCF3
Writing it this way instead of NH3CF3 serves the purpose of clarifying that it's the N that's bonded to C, and not the H. However, it is still valid to write it the second way. The first way is just meant to help you.
