Free Gift for you: Interactive Periodic Table In this way, the elements of the same group show similar chemical properties and they also have the same number of valence electrons. They have a soft structure and due to this, it. They are soft and can be cut easily with a kitchen knife.Īlso all the elements of group 1 have one valence electron.Īll the elements of group 18 are chemically inert (that means they do not easily react with other elements).Īnd all the elements of group 18 have a complete octet (that means they have 8 electrons in their outer shell). The alkali metals are the Group 1A elements and that group lies in the S-block of the periodic table of elements. The elements lying in the same groups show similar chemical properties and they also have same number of valence electrons.Īll the elements of group 1 are highly reactive to water. There are total 18 vertical columns on periodic table. The meaning of ALKALI METAL is any of the monovalent mostly basic metals of group I of the periodic table comprising lithium, sodium, potassium, rubidium. Groups are the vertical columns on the periodic table.
