#### Answer:

Well if it's ""^58Co, then the atom contains 27 protons.......

#### Explanation:

The element cobalt is characterzied by the presence of 27 massive, positively charged particles, $\text{27 protons}$, in its nucleus. Since it is ""^58Co, there are $\text{31 neutrons}$, 31 massive, neutrally charged particles in its nucleus.

And since we assume that the atom is neutral, there are 27 electrons whizizng about the massive nuclear core.
