N2 - nitrogen gas - is gaseous at "room temperature". Nitrogen is about 80% of our atmosphere.
K2S, potassium sulfide, is a solid.
C8H18, or CH3(CH2)6CH3, is octane, a liquid component of gasoline.
H2O is water, a liquid at room temperature. (Unless you are an Eskimo.)

Write formulas for the following compounds phosphorus disulfide?
PS2 is the compound for that name. P= phosphorus S=sulfide and the 2 translates to a di.
What is the formula of calcium fluoride?
The reason it becomes stable is because Ca has 2 valence electrons that it wants to get rid of to become stable. F has 7 valence electrons and wants 1 more to become stable. So, TWO F atoms each take 1 of the 2 electrons from Ca. They form an ionic bond as Ca^2+ and 2F^- to make CaF2.
What is the name of the compound ionic bond of calcium and fluorine?
CaF2, Calcium Fluoride. It is useful in iron smelting
