If gravity pushes everything to its center or a centripital force, why do atoms and molecules float in the air, shouldn't they be attracted by gravity as all the mass?
Im confused

They are attracted to the centre by gravity, but because some things (such as air molecules) are less dense that others (such as rocks), they will take up positions in layers around the centre. Things that float in the air are effectively held up by the more dense things below them.

There is an other energy thermal energy which for a gaz is

E = 3/2 RT and in gazes this energy is very superior than that of gravity

No. Buoyancy (an effect of gravity) and Brownian motion both would oppose collapse to the center.
