What is Mass Number? The number of protons and neutrons combined to give us the mass number of an atom. It is represented using the letter ‘A.’ As both protons and neutrons are present in the nucleus of an atom, they are together called nucleons. For example, an atom of carbon has 6 protons and 6 neutrons. Thus, its mass number is 12. The number of neutrons is mass number-number of protons. Mass number is the sum of protons and neutrons in a particular isotope of an atom. What was the first city to have traffic lights?
