Dairy Products. Different types of algae are found in common dairy products. For example, carrageenan is a form of algae that is in many products. Yogurt, sour cream, mayonnaise, cheese and whipped cream all are known for possessing this form of algae.
Krypton was one of three noble gases discovered in 1898 by Scottish chemist and physicist Sir William Ramsay (1852-1916) and English chemist Morris William Travers (1872-1961). Ramsay and Travers discovered the gases by allowing liquid air to evaporate.
At normal temperatures, krypton and the other elements in Group 18 are extremely unreactive. The reason is that, with the exception of helium, these elements' outer electron shells are filled to capacity with 8 electrons. This satisfies the octet rule, in which a full electron shell means maximum stability.
