The professor was surprised to see the dark yellow color of liquid fluorine.

There are elements with very well known colors, such as gold or silver, but do you know the color of any other elements in the periodic table?

lots of elements in the metals and metalloids are silver or whitish silver. many gases are blue or green. sulfur is yellow. liquid oxygen is blue. nitrogen is colorless. hydrogen is colorless. phosphorous is mostly red, but has white, yellow and black forms. Iodine is purple. I think bismuth is pink. carbon is black. silicon is opaque white to white. copper is copper. cobalt is purple. calcium and potassium are white.
