If so, the compound is most likely an acid. Use the rules for naming an acid. Does the formula contain a metal (not hydrogen)? If it doesn’t, you need to use prefixes when naming because you’re dealing with a molecular (covalent) compound. Be sure to change the ending of the second element to -ide. If there is a metal, you’re dealing with.
The chemical formula is a way to represent any chemical substance using the symbol of the elements present in it. Below we have given a list of the chemical compound formulas along with the compound name, molecular weight, and molecular formula.
Let us practice by naming the compound whose molecular formula is CCl 4.The name begins with the name of the first element—carbon. The second element, chlorine, becomes chloride, and we attach the correct numerical prefix (“tetra-”) to indicate that the molecule contains four chlorine atoms.Putting these pieces together gives the name carbon tetrachloride for this compound.
Chemical Formula Writing. The procedure that can be followed when confronted with the name of a compound and you wish to write its formula is as follows: Identify the symbol of the cation (first part of the name) and the anion; Identify the valence or charge of each symbol and place it in parenthesis just above the symbol. Cations (Positive Ions) All Group 1 elements in the Periodic Table.

In either case, each half of the sentence must be able to stand on its own as a complete sentence.
Common Names and Formulas of Important Chemical Compounds. Chemical formulas provide a lot of information about chemical substances, such as how many and what atoms they are made of, as well as the way the atoms are arranged. A compound is a substance made up of a definite proportion of two or more elements. With the help of Chemical formulas.
