Atomic Structure:
- Chromium has twenty-four protons and therefore its atomic number is twenty-four.
- The average number of neutrons in a chromium atom is twenty-eight. The most common chromium isotope (Cr-52) has twenty-eight neutrons.
- The chemical symbol of chromium is Cr.
- Chromium has four electron shells and is therefore located in the fourth period of the periodic table.
- Chromium is in Group 6 in the Periodic Table, along with the elements molybdenum, tungsten, and seaborgium.
- In the Periodic Table, chromium is part of the metals region.
- When a chromium atom has a neutral charge, there are twenty-four electrons in total. There are two electrons in the innermost electron shell, there are eight electrons in the second shell, there are thirteen electrons in the third shell, and there is one electron in the outermost shell.
- All natural chromium isotopes, which there are four of, are stable.
- Chromium is in the transition metal group of the periodic table, so it is often found in metal alloys, and it has properties that both metals and nonmetals typically have.
- The average atomic weight/mass of all chromium atoms in natural chromium, which is 83.789 percent Cr-52, 9.501 percent Cr-53, 4.345 percent Cr-50, and 2.365, is 51.9961.
