Hello, I am a bit confused with the structures of elements and identifying them. How do I know if an element has a simple molecular structure or a giant lattice structure??? I know that sulfur's got a simple molecular formula, but carbon's got a giant lattice structure. Hence sulfur has a lower melting point than carbon.
Giant lattice is the same as giant ionic isn't it? Ionic/lattice is with metals bonded to non-metals like NaCl. Covalent's between non-metals and non-metals. I think only Carbon and Silicon do giant molecular (for AS levels anyway), otherwise it will be simple molecular.

Thanks a lot
You just gotta learn them ...
B, C, Si Giant covalent (although carbon also forms fullerenes) Metals = metallic non-metals = simple molecular noble gases = atomic
