There are 18 groups (columns) in the periodic table. Group 1 (also known as the alkali metals) is the column on the far left of the table. Elements in the same group have similar, but not identical characteristics. This is because they all have the same number of electrons in their outermost shell.
The Alkali Metals are the first group in the periodic table. They include Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.The Alkali Metals have closer similarities between the elements than in any other group of the periodic table.For example each element shares the physical characteristics of being soft and silvery in color.. Alkali Metals constitute group 1 of the Periodic Table (Other than Hydrogen). They are named Alkali Metals because when they are mixed with water they form special solutions called alkaline solutions.
