How many protons, electrons, and neutrons are present in an atom of copper whose atomic number is 29 and whose mass number is 64? Gather information. The atomic number of copper is 29. The mass number of copper is 64. Plan your work. The atomic number indicates the number of protons in the nucleus of a copper atom. A copper atom must be electrically neutral, so the number of electrons equals the number of protons. The mass number indicates the total number of protons and neutrons in the nucleus of a copper atom. Calculate. atomic number (29) = number of protons = 29 number of protons = number of electrons = 29 mass number (64) - atomic number (29) = number of neutrons = 35 Verify your results. number of protons (29) + number of neutrons (35) = mass number (64)
