The others are soft metals that react violently with water to release hydrogen gas, which either bubbles off or spontaneously ignites depending on how far down you are on the table.Ĭlick any element below to see all the samples of that element. Such was the case when IUPAC recently reviewed elements 113, 115, 117 and 118, and decided to give them official names and symbols (goodbye, ununseptium and hello, tennessine). Hydrogen is an anomaly: It's traditional to put it in this column, but it really has very little in common with the rest. Characteristics of alkali metals are: High reactive metals.
As a rule, you wouldn't want any around the house in pure form, though as a compound they can be quite tasty. The alkali metals are found in group 1 of the periodic table. Every element in this family has one valence electron that they will lose in order to achieve a pseudo-noble gas configuration. Alkali metals are named such because they react with water to form alkaline, or basic, solutions. The elements in group 1 of the periodic table are referred to as the alkali metals. The reaction with water also generates hydrogen gas and a base. The first column in the periodic table are the Alkali Metals. React with acids, water, oxygen and halogens, but not always as violently as alkali metals. The Alkali Metals comprise the left-most column of the periodic table.
