Number of neutrons = Mass number - Atomic number = 54 - 24 = 30
All isotopes of Chromium (Cr) will always have 24 protons.
The most common isotope of chromium is Cr-52. To determine the most common isotope of any element, look at the periodic table and find the element in question. Chromium is number 24, Cr. The atomic mass is 51.996 amu. That's the average atomic mass. The most common isotope has the mass of the nearest whole number to 51.996. The most common isotope of chromium would then be Cr-52, with a mass of 52. Cr has 24 protons, and 24 electrons. Cr-52 would have 52-24= 28 neutrons.
There are 24 protons in Chromium (Cr). The atomic number of an element is the same as the number of protons.
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.
The isotope Cr-54 has 24 electrons.

There are 24 protons in Chromium (including Chromium54) of any isotope. Isotopes are just elements with different numbers of neutrons. If it is called chromium it has 24 protons. The atomic number of an element is the same as the number of protons.
Chromium is in the d block. It contains 24 protons.

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.
There are 24 protons in Chromium (Cr). The atomic number of an element is the same as the number of protons.
There are 24 protons in Chromium (Cr). The atomic number of an element is the same as the number of protons.
Since n + p = m, it follows that neutrons = 54 - 24 = 30,because number of protons (p) is the atomic number (34)! That's how the periodic table is organized.
