A typical atom of cobalt contains 32 neutrons. Cobalt's atomic number is 27, so that's 27 protons. Its average atomic mass is about 59, so 59-27=32. Note: different isotopes of cobalt will have either more or less neutrons than 32, but most likely, cobalt's most abundant isotope has 32. The atomic mass value on the periodic table, which is 58.933, is a weighted average of all cobalt's isotopes.

Keep in mind that the atomic mass of an element is based on an average of relative abundance of stable isotopes. Nickel has several stable isotopes and Cobalt I believe has only one stable isotope. The weighted average proportionally to the relative abundance of the several Nickel isotopes is less than the average of Cobalt's isotope(s). So basically Though Nickel has a greater atomic number and the trend is for this to correlate with atomic mass because nickel exists in relatively large proportion as a lighter stable isotope Nickels average atomic mass is less than Cobalt's atomic mass. Google about relative abundance and calculating atomic mass to find all sorts of interesting things!
