WebApr 6, 2024 · Writing formulas for ionic compounds containing polyatomic ions involves the same steps as for a binary ionic compound. The cation is written first in the chemical formula followed by the anion. Consider potassium nitrate. Potassium is located in Group IA of the periodic table, so it forms ions with a 1+ charge, K +.

WebChemical formulae provide insight into the elements that constitute the molecules of a compound and also the ratio in which the atoms of these elements combine to form such molecules. For example, the chemical formula of water, which is H 2 O, suggests that two hydrogen atoms combine with one oxygen atom to form one molecule of water. WebThe following examples will demonstrate how this rule is applied in writing the formula of a compound: 1. Write the formula for potassium bromide. Looking at the list of oxidation numbers in Table 1, it is found that potassium, K, has an oxidation number of +1 and bromide (the combined form of bromine), Br, has an oxidation number of -1. Writing WebThe number of atoms is determined by the subscript attached to the symbol. So a chemical formula of water, i.e H 2 O has two atoms of hydrogen and a single atom of oxygen.
