How do you find the atomic number
WebTo calculate the numbers of subatomic particles. in an atom use its atomic number and mass number: number of protons = atomic number number of electrons = atomic number WebThe mass number is approximately equal to the atomic mass, which is the mass of a single atom of a element measured in atomic mass units (amu). The atomic mass of Hydrogen is 1.00797 amu and the atomic mass of Carbon is 12.011 amu. The atomic mass is typically listed in the periodic table below the element's name.
