I was thinking about liquids, and I started to wonder theses related questions:

1) Besides mercury, what elements are naturally liquid at room temperature?

2) What naturally found family of substances/mixtures that do not contain $\ce{H2O}$ are naturally liquid at room temperature?

    $\begingroup$ Strange that you didn't think of ethanol ;) there are also lots of other organic and also inorganic liquids. $\endgroup$ – Mithoron May 6 '15 at 23:03
  • $\begingroup$ duh! of course! I totally forgot about ethanol! $\endgroup$ – Francisco Noriega May 6 '15 at 23:12

    $\begingroup$ This non-exhaustive list of substances contains 6179 entries which melt at or below 25°C. A few hundred of those are probably gasses at ambient conditions, a few hundred more are repeat entries for a same substance, and a large chunk of the rest is likely represented by some rather exotic compounds. Either way, goes to show there are a lot of possibilities. $\endgroup$ – Nicolau Saker Neto May 7 '15 at 3:15
  • $\begingroup$ (1) is readily answered by looking at most periodic tables. (2) is an extremely long list which SE is not suitable for. $\endgroup$ – Jon Custer May 19 '16 at 12:48

This question is a bit broad in terms of the sheer amount of chemical compounds and mixtures that are liquid at room temperature. Examples include:

Compounds
Acids, bases, many hydrocarbons (e.g. hexane) and many more

Mixtures
Crude oil, aqua regia and many more

In terms of elements, there are only two that are liquid at room temperature (say about 20 °C or 293 K):

Francium, cesium, gallium and rubidium are close, with melting points at 300 K, 301.59 K, 303.3 K and 312.46 K respectively.

LennTech provides a list The elements of the periodic table sorted by melting point

  • $\begingroup$ Sorry, I guess I was thinking on naturally ocurring compounds and mixtures, and also elements. Milk however, gets its liquidness because of the water in it no? It's basically water + other stuff. I guess I meant I meant mixtures that do NOT have h20 in it $\endgroup$ – Francisco Noriega May 6 '15 at 23:08

    $\begingroup$ The examples I gave are natural, acids, bases, hydrocarbons etc don't have water in them. $\endgroup$ – user15489 May 6 '15 at 23:09
