How do you write formula for polyatomic ions?
How do you write formulas for compounds with polyatomic ions? The cation is written first in the name; the anion is written second in the name. Rule 2. When the formula unit contains two or more of the same polyatomic ion, that ion is written in parentheses with the subscript written outside the parentheses. Click to see full answer.
What is the most common polyatomic ion?
Most of the common polyatomic anions are oxyanions, conjugate bases of oxyacids (acids derived from the oxides of non-metallic elements ). For example, the sulfate anion, S O 2− 2 O . The second rule looks at the number of oxygens in an ion.
