How to fill out formulas and oxidation numbers

How to fill out formulas and oxidation numbers

1. To fill out formulas, you need to understand the chemical elements and their symbols that are involved in the compound.
2. Start by identifying the elements present in the compound and write down their symbols.
3. Next, determine the number of atoms of each element in the compound and write it as a subscript next to the element's symbol.
4. If there is more than one atom of an element, use parentheses and then write the number of atoms as a subscript outside the parentheses.
5. Finally, balance the overall charge of the compound by adding the necessary charge to certain elements.
6. To determine oxidation numbers, first remember that oxidation number is a concept that describes the electrical charge of an atom.
7. In a neutral compound, the sum of oxidation numbers is always zero.
8. For elements in their elemental form, the oxidation number is zero.
9. The most electronegative element in a compound is assigned a negative oxidation number equal to its usual valency.
10. The sum of oxidation numbers for all atoms in a compound must equal the compound's overall charge, if it has one.
11. Use the rules and guidelines for assigning oxidation numbers to each element in the compound to determine their respective oxidation numbers.
