A level chem - bonding - identifying a substance

I just had a question say you were asked to describe what u would do to determine what type of bonding a substance has lets say u say is it soluble and it isn't so it could be any of the bottom 3 next u say does it conduct electricity and if it does it could be any of the bottom 2 so how would u determine which one it is?

So you’re basically trying to work out if it’s graphite or a metal? Graphite is soft? I dont know what else you could use for that

magnets maybe?

How would that work?

metals are magnetic and graphite isn't so if the substance is attracted to a magnet its gotta be graphite and not a metal

I'm not sure about either part of your sentence... not all metals are magnetic?
