Mass number - Number of neutrons= Atomic number
mass number = 80, number of neutrons = 41;
80-41=39
Atomic number for the element with mass number 80 and 41 neutrons; is 39.
Calcium has the atomic number of 20. This particular isotope of calcium, which has a mass number of 41, has 20 protons and 21 neutrons. Atomic number is unique to each element, so all you need is the atomic number and a Periodic Table to figure out which element you are looking for. The mass number is a distracter.

Each column will generally have the symbol of the element (sometimes name of the element also), the atomic number, the mass number, the state in which the element is present at room temperature. Some periodic table will also have the electronic configuration or electronegativity.
He (helium) is the second element on the periodic table.
