Answer:
27 protons, 31 neutrons, 27 electrons
Explanation:
Atomic number is equal to the number of protons and equal to the number of electrons.
So 27 = number of protons = Number of electrons.
Mass number is the sum of the number of proton and neutrons
Mass number = 58 = Number of proton + Number of neutrons
Number of neutrons = Mass number - Number of protons = 58 - 27 = 31
