Mass number of sulphate

Accepted Answer

Sulphate (SO₄²⁻) is a polyatomic ion, not an element or atom. It doesn't have a mass number as it's not a single entity with a defined number of protons and neutrons. The mass of sulphate is calculated by adding the atomic masses of sulfur and four oxygen atoms, and considering the charge.
