When ignited by heat, thermite undergoes an exothermic reduction-oxidation reaction. Most varieties are not explosive, but can create brief bursts of heat and high temperature in a small area. Its form of action is similar to that of other fuel-oxidizer mixtures, such as black powder.

In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated protective coating for other metals. Chromium is sourced from the mineral chromite, its only currently economic occurrence. Chromite is used directly in industrial foundry and refractory sands or converted into sodium dichromate for further refinement into other chemicals and chromium metal, but the main consumption is in ferrochrome furnaces to produce an alloy used by the steel industry.

Therefore, one of the 4s2 electrons jumps to the 3d5 so that it is half-filled (see video below). This give us the (correct) configuration of: 1s2 2s2 2p6 3s2 3p6 3d5 4s1.
