Do you like bananas? They are rich in potassium.

Group#: 1 //Period#//: 4 Atomic #: 19



Number of energy levels: 4 First energy level: 2 Second energy level: 8 Third energy level: 8 Fourth energy level: 1



Potassium is a akali metal. Group characteristics are that they are very reactive and do not occur freely in nature. There is only 1 electron in its outer shell and easily loss when bonding with other elements. These metals are malleable, ductile and are good conductors of heat and electricity. These metals can explode if they are exposed to water. Usually stored in mineral oil and kerosene, tarnish easily and have low melting points and densities.

Interesting Facts/Uses: - Potassium, which is usually found in seawater or plant cells, is extremely important for the normal functioning of the human body. - Vital for all animal and plant life. - Used to make soap, glass, gun powder, fertilizer, medicine supplements. - Substituted for table salt. - Used in photography Assignment 2: Classification of Matter Flowchart
