Is Mercury a metal? Why is it a liquid, rather than a solid?

Callie is right. Sort of. If the room temperature is a bit cold, less than 25 degrees Celsius, gallium will freeze to a solid.
Mercury has a solid phase too. Can't remember the exact freezing point, but they aren't used in outdoor thermometers for that reason because if it gets colder than about 25 below Fahrenheit it freezes and breaks the thermometer. Mercury has high cohesion, but not enough to overcome the kinetic energy of room temperature atomic motion, so it is a liquid at room temp.

Mercury and bromine are liquid at standard temperature and pressure. You can buy them on eBay. Some people try to build there own periodic chart of the elements.
Gallium melts at 85.5763 °F By mixing gallium and indium it's possible to make a eutectic alloy that is liquid at room temperature, just like mercury, but the alloy is also annoyingly sticky. (Sometimes, you can find these alloys on sale at eBay) An alloy, called galistan, is composed of gallium, indium, and tin. It is liquid down to below the freezing point of water.
Cesium melts at 83.19 °F It reacts violently with water.
Francium melts at 80 °F. It is so radioactive that you will never get enough of it to see with the naked eye. There is estimated to be 340 to 550 grams in the entire earth at one time, so its abundance can be considered to be zero in practical terms.

mercury and bromine are the only two elements that are liquids at room temperature. several will melt in your had and others will melt without much coaxing, but those are the only two at room temperature. this is only because their IMF's arent as strong as solid elements and stronger than those that are gasses. mercury is a metal and bromine is a diatomic halogen.

Mercury, cesium, francium, bromine and gallium if the room is at about 90 degrees Fahrenheit
