Chromium reacts with oxygen from the atmosphere to form the oxide Cr2O3, which is a type of metal oxide that is non-destructive as opposed to iron oxide. This property is used to protect steel when chromium is added to the molten metal to form an alloy with up to 30% chromium and is commonly known as "Stainless Steel". The Chromium oxide protects the metal from further oxidizing. Chromium will react with a number of other elements if the conditions are suitable. The most common is forming a carbide by reacting with carbon during the smelting process of Ferrochrome. This is typically and unwanted reaction in the process.
Chromium is a 3d element. chromium is a metal.
It is a valence of chromium. The hexavalent chromium is present in anions as CrO42- and Cr2O72-.
Chromium fluorides are: Chromium difluoride: CrF2 Chromium trifluoride: CrF3 Chromium tetrafluoride: CrF4 Chromium pentafluoride: CrF5 Chromium hexafluoride: CrF6
Chromium don't react with water.

The specific heat of chromium at 25 0C is 23,35 J·mol−1·K−1.

Under still milder conditions, chromium metal reacts with the halogens fluorine, F2, chlorine, Cl2, bromine, Br2, and iodine, I2, to form the corresponding trihalideschromium(III) fluoride, CrF3, chromium(III) chloride, CrCl3, chromium(III) bromide, CrBr3, or chromium(III) iodide, CrI3.

Many metals including alkali metals, alkali earth metals, chromium, nickel and zinc react with dilute hydrochloric acid.
A polished finish will reflect heat back into the the jug while a dull finish will radiate more heat to the environment. The shiny jug therefore will retain heat better than the dull jug.

Chromium does not occur freely in nature. The main chromium mineral is chromite. Chromium compounds can be found in waters only in trace amounts. Many chromium compounds are relatively water insoluble. Chromium (III) compounds are water insoluble because these are largely bound to floating particles in water. Chromium (III) oxide and chromium (III) hydroxide are the only water soluble compounds.Chromium (VI) oxide is an example of an excellently water soluble chromium compounds
