questions 28 - 31 prompt
questions 28 - 31: complete the tables by filling in the correct number of protons, neutrons and electrons.
28 fill in the blank 1 point
isotope | cobalt-60
charge | 3+

protons | type your answer...

neutrons | type your answer...

electrons | type your answer...

Explanation:

Step1: Determine number of protons

Cobalt has an atomic number of 27, so protons = 27.

Step2: Calculate number of neutrons

Mass number of Cobalt - 60 is 60. Neutrons = Mass number - Atomic number = 60 - 27 = 33.

Step3: Find number of electrons

Charge is 3+, so electrons = Protons - Charge = 27 - 3 = 24.

Answer:

protons: 27

neutrons: 33

electrons: 24
