For elements with no stable isotopes, the mass number of the isotope with the longest half-life is in parentheses.
To balance a chemical equation with parentheses, treat the entire compound within the parentheses as a single entity. Balance the elements inside the parentheses first before balancing the rest of the equation. Remember to distribute the coefficients outside the parentheses to all elements within it.
Add multiply what is in parentheses and the number that is on the outside of the parentheses that is to the right or to the left.
