Ionic liquids (ILs) are composed of organic cations and either organic or inorganic anions that remain liquid over a wide temperature range, including room temperature. IL characteristics can be dramatically adjusted (e.g., hydrophobic vs. hydrophilic) by changing the anion type, or subtly altered by changing the length or number of alkyl groups appended to the cation. Changing alkyl chain ... Chlorine is a yellow-green gas at room temperature. Chlorine has a pungent, irritating odor similar to bleach that is detectable at low concentrations. The density of chlorine gas is approximately 2.5 times greater than air, which will cause it to initially remain near the ground in areas with little air movement.

In their ... It has one of the widest liquid ranges of any element. Its melting point is such that it is solid at room temperature, but will begin to melt in your hand. When gallium freezes, it expands (like water does when it freezes into ice). This means you have to be careful when storing liquid gallium to allow for expansion when the temperature drops. Ionic liquids (ILs) are composed of organic cations and either organic or inorganic anions that remain liquid over a wide temperature range, including room temperature. IL characteristics can be dramatically adjusted (e.g., hydrophobic vs. hydrophilic) by changing the anion type, or subtly altered by changing the length or number of alkyl groups appended to the cation. Changing alkyl chain ... Take into account there are actually 5 elements which are liquid near room temperature, (Mercury, bromine, francium, cesium, gallium are all liquid at 30 degrees celsius.) then there are actually more elements at a liquid state than there should be. Here is a nice website if you want to sort elements by melting point, boiling point, or other factors.
