Facts about Potassium Potassium is an “Alkali Metal”, a very reactive metal and is not found in nature The element was discovered by Sir Humphrey Davy, he also discovered calcium and sodium Recommended daily potassium intake is 4.7 g. a day

Atomic Number: The atomic number of an element is the number of protons in an atom Atom # = # of Protons Potassium's atomic number: 19

Atomic Mass The mass number of an atom is the number of protons plus the number of neutrons Mass # = Protons + Neutrons Potassium's atomic mass: 39.10
