Here's the breakdown of protons, neutrons, and electrons in cobalt:

* Protons: Cobalt has an atomic number of 27. This means it has 27 protons. The number of protons defines an element.

* Electrons: In a neutral atom, the number of protons and electrons is equal. So, cobalt also has 27 electrons.

* Neutrons: The number of neutrons can vary, resulting in isotopes of cobalt. The most common isotope is cobalt-59, which has 32 neutrons (59 - 27 = 32).

Important Note: There are other isotopes of cobalt, but cobalt-59 is the most abundant.
