The atomic number of an atom is equal to the number of protons present in the atom. The atomic mass of an atom is equal to the sum of number of protons and number of electrons present in the atom. The Number of neutron present in an atom is equal to the difference between atomic number and atomic mass. The atomic number of cobalt is 27. The atomic mass of Cobalt-60 is 60.
Atomic mass = number of proton + number of neutrons
Atomic mass = atomic number + number of neutrons
Number of neutrons = atomic mass - atomic number
Number of neutrons = 60 - 27
Number of neutrons = 33
Atomic mass = number of proton + number of neutrons
Atomic mass = atomic number + number of neutrons
Number of neutrons = atomic mass - atomic number
Number of neutrons = 60 - 27
Number of neutrons = 33
