Why do you put parentheses around a polyatomic ion?
Parentheses around a polyatomic ion in a chemical formula indicates that more than one of that ion is present in the compound. This notation helps clarify the chemical formula and the ratio of elements in the compound.
When to use parenthesis when writing ionic compound formulas?
Parentheses are used in ionic compound formulas when multiple polyatomic ions are present. The parentheses are used to indicate a subscript that applies to all the elements inside the parentheses. For example, in the formula for calcium nitrate (Ca(NO3)2), the parentheses indicate that the nitrate ion (NO3) has a subscript of 2.
How can one effectively read chemical formulas that contain parentheses?
