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
