∙ 12y agoCobalt (Co) has the common form of cobalt 60, ie its atomic mass is 60. Its atomic number is 27. Atomic mass is made up of protons and neutrons. Atomic number is number of protons. Hence number of neutrons is 60 - 27 = 33/
Since cobalt has an atomic number of 27, any isotope of it contains 27 protons and 27 electrons per atom. The isotope with mass number 60 contains (60 - 27) or 33 neutrons per atom.
16.2
The only whole number is 1, because 27 is a prime number.
Mass Number= 33+27=60
The HCF of 27 and 80 is 1
1, 3, 9, 27.
Besides 60, it would be 30.
Cobalt-60 has 27 protons, (Cobalt has an atomic number of 27) 33 neutrons (mass number less atomic number) 27 electrons in the neutral atom (balancing the charge of the 27 protons)
The number is 1.
The number 3
