Cobalt-60 is one way of writing the isotopic notation however this is the notation that you must be searching for (it is hard to write on this site):
60Co
33
It's 59.93simply saying 60... as name tells, Co-60
neutrons = (mass number)-(number of protons)
neutrons in cobalt-60 = 60-27 = 33
60 Cu
29
107Ag

Only one naturally occurring isotope of cesium is known, cesium-133 (133Cs) which is not radioactive. A number of artificial radioactive isotopes of cesium are known also. One radioactive isotope of cesium is of special importance, cesium-137. It is produced in nuclear fission reactions. Read more on cesium in the link below.
If a radioactive isotope undergoes beta emission, a. The atomic number changes B. the number of neutrons remains constant c. The mass number changes d. The todo isotope loses and electron
It's usually posted as 14C and indicates the isotope asked about.
Uranium is a radioactive element; the isotope 235 is fissile with thermal neutrons; the isotope 238 is not so fissile but is fertile (transformation in the fissile isotope plutonium 239). Consequently, uranium is a good nuclear fuel and also can be used in nuclear weapons.
The isotope of hydrogen we call tritium is radioactive because all atoms of it have an unstable nucleus. Tritium, which is hydrogen-3, has a single proton in its nucleus (as you'd expect), and has two neutrons there as well. This combination of nucleons is not stable, and it will eventually decay (with a 12.32 year half-life). Said another way, the nuclear arrangement of a proton and two neutrons is not a stable one, so atoms of this isotope of hydrogen will be radioactive and will eventually decay. When any atom is "created" by fusion or other means (including nuclear decay), the nucleons (the protons and neutrons that make up its nucleus) have to "make a deal" as to how they are going to get along in the tiny volume of space that the nucleus occupies. Some arrangements of protons and neutrons just "aren't right" and are unstable, and this gives rise to characterizing the isotope as being radioactive. Tritium (H-3) is one such isotope.
Isotopes of a chemical element have the same number of protons and electrons but a different number of neutrons.A radioactive isotope is unstable and can emit nuclear radiations.
radioactive decay
Its a radioactive isotope of copper with a half-life of about 12 hrs. It doesn't really have a specific name but to differentiate it from 'normal' copper it's called 'Copper-64' or 'Cu-64'
The rate of decay (activity) of a radioactive isotope is proportional to the number of atoms of the isotope present.
The rate of decay (activity) of a radioactive isotope is proportional to the number of atoms of the isotope present.
Copper has 29 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a copper isotope = Mass number - 29

For the nuclear reactors and nuclear weapons the isotope plutonium-239 is important.

The standard number of that atom.
The atomic number of nitrogen is 7. When it is a radioactive isotope you add the number of neutrons to the atomic number (equaling 15). You then write 15 over 7 next to a capital 'N' representing Nitrogen.
Half of a radioactive isotope is an atom that would have half of the atomic number of the radioactive isotope. In the case of radium-88 (88Ra), half of the radioactive isotope would be ruthenium-44 (44Ru). This assumes that the protons do not break down and that none are lost to additional reactions with other elements or compounds. Electrons can be lost along the radioactive chain, resulting in an ion of ruthenium rather than an electrically neutral atom.
