Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
Fundamentally, the temperature and pressure, depending on the substance. Most substances may exist in any one of those three forms under certain conditions of temperature and pressure. For example, water may exist in all three forms simultaneously (ice, liquid, vapour) under very specific conditions of temperature and pressure which are referred to as the "triple point of water".
I am assuming that you mean at room temperature and 1 standard atmosphere. Under such conditions, mercury would be a liquid.Any material's physical state is determined by its temperature and the pressure being exerted upon it. Mercury, as well as most elements/compounds, can exist in all three states if exposed to the proper conditions.
Don't they all exist in the three states of matter? Depending on the temperature...
Temperature causes the matter to exist in three different states. They are Solid, Liqid and Gas. If temperature is increased matter changes into gas and if temperature is decreased it changes into solid.
(1) Temperature (2) Nature of solute or solvent (3) and Pressure.
Any chemical has that capacity, if you create the necessary conditions of temperature and pressure. All elements and all compounds can exist as solids, liquids, or gases.
Bromine, Br2, and mercury, Hg, are the only elements that are liquids at room temperature.
Chlorine Fluorine Nitrogen Oxygen
Carbon(C),Oxygen(O) and Mercury(Hg)

The triple point of a substance is the temperature and pressure at which all three phases are in equilibrium. The exact temperature and pressure depend upon the identity of the substance.
At the super critical point. The required temperature and pressure may vary depending on the substance
science is divided in two parts .first is based on physics (Pressure, temperature,)and other-one is based on chemicals and elements.
For substances, the temperature and pressure at which all three states of matter exist in thermodynamic equilibrium is called the triple point. However, a mixture would have two or more different substances with different melting and boiling points, meaning the triple point of each would be different.

All things in a room will eventually be at room temperature.
