Dot-Cross

I don't understand how you know where and how to know if there it is a dative covalent bond within the picture below:

And also how would I know in the future? Thanks :frown:

I'm quite sure there isn't a dative covalent bond there - the square brackets [] around the dot cross diagram usually tell you that it's ionic bonding. For a dative covalent bond, both electrons in the bond will come from the same atom, so if you look at the diagram, you'll notice that on the top N-H bond, both electrons are represented as dots, so it's a dative covalent bond :smile:
