the alkali metal is said to be oxidized, and whatever takes the electron from the alkali metal is reduced. All of the alkali metals like to give up their single valence electron," saysDr. Chip Nataro, chemistry professor at Lafayette College...
Alkali metals are the six elements that comprise Group I in the Periodic Table: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Especially when dissolved in water, these elements form strong bases (alkalis) capable of reacting with and ...

7.1.1 Alkali metal IIPs The alkali metals are the six metallic elements in Group 1 of the periodic table, namely Li, Na, K, Rb, Cs, and Fr. The first five exist in nature, whereas Fr is only produced through nuclear reaction. The alkali metal ions generally have smaller atomic radii ...
Location of the Alkali Metals on the Periodic Table The alkali metals are the elements located in Group IA of theperiodic table. The alkali metals are lithium, sodium, potassium, rubidium, cesium, and francium. Alkali Metal Properties The alkali metals exhibit many of the physical properties comm...
