27number of protons is the same as the 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 number of Cobalt is 27.
Cobalt has a lower atomic mass than lead. The atomic mass of cobalt is approximately 58.93 g/mol, whereas the atomic mass of lead is about 207.2 g/mol.
Cobalt, is in the metal family. The atomic number for the element of cobalt, (word steaming from the German meaning for evil spirit, and goblin) is twenty seven.
Cobalt has an atomic mass of 58.933195(5) while nickel has an atomic mass of 58.6934(4). Nickel has the lower atomic mass.
Interestingly, nickel has a lower atomic mass (58.693) than cobalt (58.933), even though cobalt has a lower atomic number (27) than nickel (28).
