The only non-metal element that is a liquid at room temperature I know of is Bromine of group 7.
At room temperature, only 2 elements are liquids. One is Mercury (metal) and the other is bromine (non-metal). They are both highly dangerous substances.
Carbon is always solid at 20 degrees in any commonly used scale.
Solid, assuming normal atmospheric pressure.
Gaseous state. The boiling point of radon is -71 degrees C. So at 20 degrees C, it is above the boiling point and is a gas at this temperature.
Every gas has a different liquidation temperature based on what element it is. Hydrogen has a liquidation point of 423.17 degrees below zero F. Or 20.28 degrees K. That is 20 degrees above absolute zero.
No it is not! Room temperature is 20 deg C. Osmium becomes a gas at 5012 deg C: a lot, lot hotter!!
Niobium is a solid metal at 20 C.
It's a solid.
Solid
Hydrogen is a gas at 20 degrees, Fahrenheit and Celsius, but it you are talking Kelvin, then it is a liquid.
Vanadium is a solid metal at 20 0C.
It's a solid.
Carbon is always solid at 20 degrees in any commonly used scale.
Nitrogen ice is solid. Liquid nitrogen is liquid. At standard temperature and pressure, nitrogen is gaseous.
Ammonia (NH3) is a (very 'water' soluble) gas
Solid, assuming normal atmospheric pressure.
Sulfur is a solid at room temperature(20 degrees Celsius)
First off you need to be more specific. Are you refering to 20*C or 20*F? Luckily Vanadium is a metal and it is a solid at either F or C but you need to make sure to specify.
