How to fill out naming and writing formulas

How to fill out naming and writing formulas:

1. Start by identifying the elements present in the compound or molecule. This can be done by observing the atoms or ions involved.
2. Determine the type of compound or molecule being represented. Is it an ionic compound, covalent compound, or an acid?
3. If it is an ionic compound, write down the symbols of the elements involved, indicating the charge of each ion. The positive ion (cation) is usually written first, followed by the negative ion (anion).
4. Use subscripts to indicate the number of each ion needed to achieve a neutral charge. The subscripts should be the smallest possible whole numbers.
5. If it is a covalent compound, use prefixes to indicate the number of atoms of each element. The prefixes used include mono-, di-, tri-, tetra-, penta-, and so on.
6. In the case of acids, the naming and writing formulas can be a bit different. For binary acids, start with the prefix "hydro-" followed by the non-metal element name, and then add the suffix "-ic". For oxyacids, start with the polyatomic ion name (usually ending in "-ate" or "-ite") and add the prefix "per-" for the higher oxidation state or "hypo-" for the lower oxidation state. Finally, add the suffix "-ic" or "-ous" accordingly.
7. It is important to consider any special rules or exceptions that may apply when naming and writing formulas for certain compounds or molecules.
