How to write chemical compound names and Formula?
Chemical compound names and formula can be very complex. Naming conventions vary by chemical compound type and involve Greek prefixes and knowledge of how chemicals react to one another. Below is a simplified guide on how to correctly write chemical names and formula in your research paper so you can get started!
Which is the second element in a covalent compound?
In our sample element, CF 4, fluorine is the second element, so we'll write it at the end. Be sure to add the -ide ending, like this: "Carbon tetrafluoride". Notice that the Greek prefix and the second atom form a single word together. They are never written as 2 separate words.
How is the formula for a covalent compound written?
It is customary to prefix the name of one atom of the second element with mono-. For example, CO is named carbon monoxide rather than carbon oxide. You can write the formula for a covalent compound from its name by writing the symbols for the first and second elements and translating the prefixes into subscripts.
How are prefixes used to write covalent compounds?
Writing covalent compounds involves the use of Greek prefixes. They are listed in the table to the right. The prefixes are used to indicate the amount of each atom in the compound. The first element never uses the prefix mono-, but does use all others.
