Properties of chromium

Transition metals, also called transition elements is the group to which chromium belongs. In this group of chemical elements to which chromium belongs, there are those located in the central part of the periodic table, specifically in block d. Among the characteristics that chromium has, as well as those of the rest of the transition metals, is that of including in its electronic configuration the d orbital, partially full of electrons. Properties of this type of metal, among which is chrome, are its high hardness, having high boiling and melting points and being good conductors of electricity and heat.

The state of chrome in its natural form is solid. Chromium is a metallic silver-looking chemical element and belongs to the group of transition metals. The atomic number for chromium is 24. The chemical symbol for chromium is Cr. The melting point of chromium is 2130 degrees Kelvin or 1857.85 degrees Celsius or degrees Celsius. The boiling point of chromium is 2945 degrees Kelvin or 2672.85 degrees Celsius or degrees Celsius.

Uses of Chromium

Chromium is the first element in Group 6 of the periodic table. If you’ve ever wondered what chrome is for , here is a list of its possible uses:

  • Magnetic tape (used in audio cassettes and high-end audio tapes) is made of a chrome magnetic compound.
  • Chromium (III) oxide is a polished metal oxide better known as chrome green.
  • In science labs, chromic acid is used to clean glassware if you have traces of organic compounds.
  • The leather is tanned using chromium (III) salt ions.
  • Different chromium compounds are used to make different color pigments and tints. School buses are usually painted using chrome yellow. Currently, alternatives are used due to environmental concerns. Chrome red and chrome green are still the most common colors.
  • Wood is preserved through the use of chromium (VI) salts.
  • Stainless steel, used in many applications, is made when chromium is added to iron . Stainless steel knives contain chrome.
  • Iron, nickel and chromium alloys are very strong and withstand very high temperatures. They are used in jet engines and gas turbines.
  • Chrome is quite hard and is resistant to corrosion. For this reason, many things are covered in chrome. A lot of metal things that we use on a daily basis (knives and forks for example) are coated with chrome.

Atomic properties of chromium

The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find chromium within the periodic table of the elements, chromium is in group 6 and period 4. Chromium has an atomic mass of 51.9961 u.

Chrome’s electronic configuration is [Ar] 3d54s1. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. The average radius of chromium is 140 pm, its atomic radius or Bohr radius is 166 pm, and its covalent radius is 127 pm. Chromium has a total of 24 electrons, the distribution of which is as follows: In the first layer it has 2 electrons, in the second it has 8 electrons, in its third layer it has 13 electrons and in the fourth it has 1 electron.

››Details on molecular weight calculations

In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.

If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.

Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights.

Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.

Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.

Atomic Mass Of Chromium-52

A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying to convert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.

The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. We use the most common isotopes. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.
