How do you tell if a element is a gas solid or liquid on the periodic table?

Answer 1

A Periodic Table that's big enough will display the "phase" of the element--is it a solid, liquid or gas at 25C? There are only two elements that are liquid at that temperature--bromine and Mercury. Eleven elements are gases--hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon. Everything else is a solid, or an unknown--the synthetic elements from 104 on don't last long enough to get a handle on their phases.

This is a fun thing: at http://www.ptable.com you will find a periodic table with a temperature slider--set it to, say, 300C and you can see the phases of all elements at that temperature.

Answer 2

Almost every element can exist as either a solid, a liquid, or a gas, depending upon temperature and pressure. The single exception is helium which has no solid phase at any temperature or pressure; it can only exist as either a gas or a liquid. The periodic table of elements does not get into the details of the phase changes of the elements which it lists. If you require detailed information about elements, you can find it in the Handbook of Physics and Chemistry (among other places; there is also wikipedia, of course).
