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.
Mass Number= 33+27=60
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 only naturally occurring isotope of As (atomnumber 33) is As-75 (76 and 77 have decay half-time of several houres)This As-75 has 33 protons, 33 electrons and (75-33 =) 42 neutrons
The isotope 60Co: 59, 933 817 1(7)
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.
Mass Number= 33+27=60
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)
Cobalt (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/
The atomic number of an atom is the number of protons, so this atom has an atomic number of 27, which makes it cobalt, with the symbol Co. The isotope of cobalt that contains 27 protons and 27 neutrons has a mass number of 54, which is the sum of the protons and neutrons in the nucleus of the atom.
The only naturally occurring isotope of As (atomnumber 33) is As-75 (76 and 77 have decay half-time of several houres)This As-75 has 33 protons, 33 electrons and (75-33 =) 42 neutrons
13 protons and 14 neutrons
The isotope 60Co: 59, 933 817 1(7)
The atomic masses of two isotopes of cobalt are 59 and 60. What is the number of protons in each?
18. Phosphorus has an atomic number of 15, therefore it has 15 protons. Phosphorus-33 has a total of 33 protons and neutron and therefore has 18 neutrons. Phosphorus-33 is a synthetic unstable isotope of P.
27 protons are the number above the symbols
The element cobalt has 27 protons. Since the sum of the number of protons and neutrons in your particular question is 59, the answer to what has 27 protons and 32 neutrons is the particular isotope of cobalt labeled 59Co. This is cobalt's only stable isotope.
