Alkali Metal Particles

Patent Pending The alkali metals are a group in the periodic table consisting of the chemical elements lithium (Li), sodium (Na),[note 1] potassium (K),[note 2] rubidium (Rb), caesium (Cs),[note 3] and francium (Fr).[4] This group lies in the s-block of the periodic table[5] as all alkali metals have their outermost electron in an s-orbital.[6][7][8] The alkali metals provide the best example of group trends in properties in the periodic table,[6] with elements exhibiting well-characterized homologous behaviour.[6]
