Hey guys, I'm in my preliminary year for chemistry this year and I want to ask, what's the difference between ionic, covalent molecular, covalent lattice and metallic substances? I've searched literally everywhere and I still don't understand :(
Sorry for the dumb question, thanks!! :)

Ionic is quite simple. The components of ionic compounds are ions. This means they are charged particles. This arises when one atom donates (or equivalently accepts) electron(s) from another atom.
E.g. sodium ion (Na less one electron): Na-
Covalent molecular and covalent network are similar. Covalent compounds always involve electrons being shared between molecules.
Covalent molecular would be like carbon dioxide. Covalent network would be the allotropes of carbon - graphite and diamond to name examples. The difference is that covalent networks go on forever, whereas covalent molecular are just small single units.
Metallic substances are easy, it's just a ton of metal atoms bonded to each other. E.g. a pure sheet of copper has nothing but Cu in it.

Thank you!! This clarified everything that i needed :D :D
