  1. Most important elements on earth: carbon and silicon • Allotrope: molecular form of an element that exists in two or more different forms in the same physical state. • Examples for carbon: diamonds, graphite, and buckminsterfullerene. • What are carbon-containing compounds called in general? Organic compounds ii. Group propertiesC. Group 14 (4a)

  2. This group has all three different categories of metals: metals, non-metals, metalloids One method used to isolate pure N2: combine and then distill it from a liquefied oxygen. Liquid nitrogen distills off first because it has a lower boiling point than liquid oxygen. The Haber process is used to make ammonia by combining hydrogen and nitrogen. Fe Reaction for the Haber process: N2 (g) + 3H2 (g) ⇔ 2NH3 (g) N2 is extremely stable because it has a triple bond. D. Group 15 (5a)
