- Carbon (from Latin carbo ‘coal’) is a chemical element; it has symbol C and atomic number 6. It is nonmetallic and tetravalent—meaning that its atoms are able to form up to four covalent bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table. Carbon makes up about 0.025 percent of Earth’s crust. Three isotopes occur naturally, 12C and 13C being stable, while 14C is a radionuclide, decaying with a half-life of 5,700 years. Carbon is one of the few elements known since antiquity.

William Penn Adair Rogers (November 4, 1879 – August 15, 1935) was an American vaudeville performer, actor, and humorous social commentator. He was born as a citizen of the Cherokee Nation, in the Indian Territory (now part of Oklahoma), and is known as “Oklahoma’s Favorite Son”. As an entertainer and humorist, he traveled around the world three times, made 71 films (50 silent films and 21 “talkies”), and wrote more than 4,000 nationally syndicated newspaper columns. By the mid-1930s, Rogers was hugely popular in the United States for his leading political wit and was the highest paid of Hollywood film stars. He died in 1935 with aviator Wiley Post when their small airplane crashed in northern Alaska.
