Alkali metals are highly reactive at standard temperature and pressure and readily lose their outermost electron to … The alkali metals are softer than most other metals. Alkaline earth metals are more stable than alkali metals. Alkali metals have low ionization energies. [ Rn] 7s 1. 2, 8, 18, 32, 18, 8, 1. They react when coming into contact with water. They all have one valence electron in the outermost shell which they seek to lose in order to have a full outer shell. This quiz game will help you memorize all the alkali metals with ease. The elements in the periodic table are classified in such a way that their properties are observed similar at periodic intervals. They are a very different family, even though they have a similar name. There are alkali metals all around you right now. Examine Your Periodic Table. 94 times. It is the first group of s-block, Despite the presence of hydrogen at the top of the group (1A), It is not one of the alkali metals but it is one of the nonmetals because it has a small atomic size and it is a gas. Hydrogen and the alkali metals make up the group 1 elements of the periodic table. The compound ammonium has very similar properties to the heavier alkali metals. Alkali metals make up six different elements found in the first column of the periodic table. Alkali metals: The alkali metals make up most of Group 1, the table's first column. This group lies in the s-block of the periodic table as all alkali metals have their peripheral electron in an s-orbital: this common electron setup results in fundamentally extremely similar characteristic features. 0.
