Black powder, flash powder, KP, H3, Armstrong's mix, willow, and their are others that just have generic names such as blue star #1.
Covalent compounds, particularly binary compounds consisting of two nonmetals, use prefixes in their names to indicate the number of atoms of each element present in the molecule. This helps distinguish between similar compounds with different ratios of atoms.
Some types of compounds that use prefixes in their names are covalent compounds, particularly binary covalent compounds formed between nonmetals. These prefixes indicate the number of atoms of each element present in the compound. Examples include carbon dioxide (CO2) and dinitrogen tetroxide (N2O4).
The names and chemical formulas for five compounds in which Krypton exists are Krypton Tetrachloride (KrCl4), Krypton Difluoride (KrF2), Krypton Hexabromine (KrBr6), Krypton Dichromate (Kr2Cr2O7), Krypton Chromate (KrCrO4)
because they are the 1st discoverers.
Some examples are copper(II) sulfate, copper(I) chloride, copper(II) chloride, copper(II) carbonate.

some compounds are composed of molecules bound by ionic compounds so no
