One of the most interesting part of this redox reaction is that the majority of the carbon dioxide formed is itself reduced when it comes to contact with the unburned coke and produce more reducing agent.

List each subshell, and then fill each subshell with an appropriate number of electrons until all electrons in the element are accounted for. Transition elements have electrons in the d orbital, which introduces some additional nuance in the electron configurations.

There are 118 known elements, including 98 naturally occurring and 20 synthesized, with examples like oxygen, iron, and gold. Elements differ in value, with gold being highly prized compared to cheaper elements such as aluminum.

It is a very common element, fourth most abundant in the earth's crust. In addition, two of the ten most common compounds in the earth's crust are the two common oxides of iron.

It also explains the decomposition of calcium carbonate into calcium oxide and carbon dioxide, which requires temperatures exceeding approximately 835°C. Below this temperature, the products are not detectable, but measurable carbon dioxide is produced above 700°C. The quicklime production process leverages the removal of carbon dioxide to favor product formation.

In the case of first row transition metals, the electron configuration would simply be [Ar] 4s x 3d x . The energy level, "n", can be determined based on the periodic table, simply by looking at the row number in which the element is in.
