The correct statement about the model of a cobalt atom is:
The model should show 27 protons and 32 neutrons.
Explanation:
- The atomic number (27) indicates the number of protons in a cobalt atom.
- The mass number (59) is the total number of protons and neutrons in the atom. To find the number of neutrons, you can subtract the number of protons from the mass number:
59 (mass number) - 27 (protons) = 32 neutrons.
