A:
Ordinary nitrogen molecules freeze into a standard solid if you get
them cold enough, about 63 K or -210 Celsius. There are countless
nitrogen compounds (molecules which contain nitrogen and other
elements) and these too generally freeze into solids. For example, the
simple compound urea is solid at room temperature, and doesn't melt
until heated to 135 Celsius, above the boiling point of water.
