I still don't know. Help!

Basically in periods and groups, how can you tell which elements are solid, which are gases/liquids??? I still don;t know, this is why i get so many easy questions wrong! HELPP!! I feel so dumb!
well you can't really say from the periods or groups... you have to know what kind of bonding it will have... if its covalent... like Cl2.. its going to a gas but something like S8, is likely to solid, because of high van-der waals forces.. similarly Si is damn hard, because of its giant covalent structure...

in normal conditions, metals are in general solid, apart from mercury, which is a dense, silver liquid. Metalloids are solid, carbon, sulphur, selenium and phosphorus too. In group 15 the only gas is nitrogen, in group 16 it's only oxygen, in group 17 fluorine and chlorine are gases, bromine is a very dark purple liquid, iodine and astatine are solid. group 18 is all noble gases, and hydrogen is a gas too.
Thanks guys.
