(1) A nonmetallic univalent element belonging to the halogens; usually a yellow irritating toxic flammable gas; a powerful oxidizing agent; recovered from fluorite or cryolite or fluorapatite

(1) The halogens are a group of chemical elements that includes fluorine , chlorine, bromine, iodine, and astatine.
(2) The elements hydrogen, nitrogen, oxygen, fluorine , chlorine, bromine and iodine consist of diatomic molecules.
(3) A hydrogen bond is a dipole dipole interaction that occurs between any molecule with a bond between a hydrogen atom and any of oxygen / fluorine / nitrogen.
(4) As its position in the periodic table would suggest, it is less active than the three halogens above - fluorine , chlorine, and bromine.
(5) Potassium also reacts readily with all acids and with many nonmetals, such as sulfur, fluorine , chlorine, phosphorus, and nitrogen.
