Radium (not to be confused with radon)
Naturally, it can only have 58 neutrons. Synthetic isotopes however can have between 44 and 77 neutrons to this date.
58 electrons because the number of electrons is the same number of protons [] [] () (---------------------)
We can find Cerium as a non metal element. Atomic number of it is 58.
The element platinum (Pt) has 78 protons in the atomic nucleus.
Assuming that the questioner intended to write "Cr" instead of "cr", the isotopes indicated are those of the element chromium, whose atomic symbol is "Cr" and whose atomic number is 24. The atomic number is defined as the number of protons in a nucleus of each atom, and the atomic mass number, which precedes the atomic symbol, is defined as the number of protons and neutrons combined. In order to maintain electrical neutrality as is required for any atom, the number of electrons must be the same as the number of protons. From the definition of mass number, it follows that the number of neutrons is equal to the atomic mass number minus the atomic number. Therefore, each isotope named in the question has 24 protons and 24 electrons, but the isotope with mass number 58 has 32 neutrons and the isotope with mass number 63 has 32 neutrons has 39 neutrons.

Nickel (Ni) is a chemical element with the chemical symbol Ni and atomic number 28. Nickel has: protons=28 neutrons=30 electrons=28 atomic mass=58 atomic #=28
Neutrons: 58 Electrons: 45 Protons: 45
One can ignore the scant contribution of electrons to atomic mass. Simply add the number of protons and neutrons to obtain 53. Please see the link.
Rhodium has 45 protons, 45 electrons and 58 neutrons.
Cerium's atomic number is 58. Thus, to be electrically neutral, cerium must have 58 protons and 58 electrons. 140Ce is its most abundant isotope with 140 - 58 = 82 neutrons.

For any element, this is answered in the same way. The mass number is the number of protons plus the number of neutrons, in this case 50. The atomic number is the number of protons. Subtract the atomic number from the mass number to give the number of neutrons. For any element, this is answered in the same way.

The atomic number always gives the number of protons or electrons. The neutrons are obtained by subtracting the number of protons from the atomic mass. In this example, since 45 is the atomic number, this element has 45 protons. since the mass is 92, the number of neutrons is 92-45= 47. However, this is not really true because the element with 45 as atomic number is rhodium and it has a mass of 103 u and hence a total of 58 neutrons.
