What is the atomic symbol atomic number and atomic mass of an atom that has 27 protons 27 neutrons and 27 electrons?
The atomic number of an atom is the number of protons, so this atom has an atomic number of 27, which makes it cobalt, with the symbol Co. The isotope of cobalt that contains 27 protons and 27 neutrons has a mass number of 54, which is the sum of the protons and neutrons in the nucleus of the atom.
