- How is the mass number related to the number of protons and neutrons an atom has?arrow_forwardWhat particles are found in the nucleus of an atom? What is the charge of the nucleus?arrow_forwardThough the common isotope of aluminum has a mass number of 27, isotopes of aluminum have been isolated (or prepared in nuclear reactors) with mass numbers of 24, 25, 26, 28, 29, and 30. How many neutrons are present in each of these isotopes? Why are they all considered aluminum atoms, even though they differ greatly in mass? Write the atomic symbol for each isotope.arrow_forward
