What is cobalts atomic number?

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.

The atomic masses of two isotopes of cobalt are 59 and 60 what is the number of protons and neutrons in each?

For the isotope with an atomic mass of 59, which is cobalt-59, it has 27 protons and 32 neutrons. For cobalt-60, it has 27 protons and 33 neutrons. This is because the atomic mass includes both protons and neutrons, so subtracting the atomic number (equal to the number of protons) from the atomic mass gives the number of neutrons.
