Discovery of DNA. Today, we know that DNA is the genetic material: the molecule that bears genes, is passed from parents to children, and provides instructions for the growth and functioning of living organisms. But scientists didnât always know this.

The alkali metals Lithium, Sodium, Potassium, Rubidium cesium and Francium is the most reactive group of metals. They are this way because they only need to lose one electron to gain a stable octet which is very favorable energetically. The most reactive group of non-metals is the halogens, Fluorine, Chlorine, Bromine, Iodine and Astatine. These are the exact opposite. They are extremely reactive because they only need to gain one electron to gain a stable octet which is again, highly energetically favorable.
