Iron

Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where the production of nickel-56 (which decays to the most common isotope of iron) is the last nuclear fusion reaction that is exothermic. Consequently, radioactive nickel is the last element to be produced before the violent collapse of a supernova scatters precursor radionuclide of iron into space.

Like other group 8 elements, iron exists in a wide range of oxidation states, −2 to +6, although +2 and +3 are the most common. Elemental iron occurs in meteoroids and other low oxygen environments, but is reactive to oxygen and water. Fresh iron surfaces appear lustrous silvery-gray, but oxidize in normal air to give hydrated iron oxides, commonly known as rust. Unlike many other metals which form passivating oxide layers, iron oxides occupy more volume than the metal and thus flake off, exposing fresh surfaces for corrosion.

Kick Six

The Kick Six (alternatively referred to as Kick Bama Kick, in reference to Punt Bama Punt) refers to the final play of the 78th Iron Bowl college football game played on November 30, 2013 at Jordan–Hare Stadium in Auburn, Alabama. The game featured No. 1-ranked and two-time defending national champion Alabama Crimson Tide (11–0, 7–0 in the SEC) as a 10-point favorite over the No. 4-ranked Auburn Tigers (10–1, 6–1 in the SEC). At stake was the outright SEC West title and a berth in the 2013 SEC Championship Game.

The game was notable for its ending; Auburn tied the game 28–28 with 32 seconds remaining. With one second remaining in regulation, Alabama missed a 57-yard field goal. Auburn's Chris Davis caught the errant kick and returned it 100 yards (under NCAA rules) to the opposite end zone, scoring a touchdown; the runback tied LSU's Odell Beckham Jr.'s record-setting 100 yard return that same season.

The game, which was televised by CBS, posted an 11.8 television rating during the final half hour, which was the highest rating ever achieved during a college football broadcast at that time. Some sports writers argued that Davis' play was the single greatest moment in college football history.
