Since chromium has an atomic number of 24, each atom of it contains 24 protons. The number of neutrons can be found by subtracting the atomic number from the mass number. Thus, chromium-63 has 39 electrons.
Chromium's, or Cr's, atomic number is 24. Therefore each chromium atom has 24 protons. 52Cr is the most stable isotope of chromium and has 52 - 24 = 28 neutrons. The chromium ion, Cr3+, means it has 3 less electrons than neutral chromium, and thus the number of protons and neutrons are unaffected.

Number of neutrons = Mass number - Atomic number = 54 - 24 = 30
There are 24 protons in Chromium (Cr). The atomic number of an element is the same as the number of protons.

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 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.
number of neutrons = mass number - atomic number = 50 - 24 = 26

A typical chromium atoms has 28 neutrons. Because electrons are so small, virtually all of the atomic mass comes from the protons and neutrons. By subtracting the number of protons (equal to the atomic number) from the total atomic mass, the number of neutrons is obtained. For chromium atomic mass- 52 atomic number (number of protons) - 24 number of neutrons 52-24=28
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.
