Alkali metals

Some of representative elements groups are known as regular groups, Because their elements show a great regularity & graduation in their properties and

Comparing halogen reactivity trends with those of the alkali metals. Halogens become less reactive down the group as it becomes harder to gain an extra electron.

Alkaline Earth Metal: An element in Group 2 of the periodic table.

Potassium and its close periodic table neighbor sodium are solids at room temperature. Their alloys however are not.

In this section i am going to talk about Chemical Families. The red section is the section which contains all the Alkali and Alkaline earth metals. Now for those of you who don't know what an alkali or an earth metal is they are a group of chemical elements in the periodic table with very similar properties e.g. Mg, Ca, Sr ect. The blue section is the transition metals which i have already talked about. The orange is Halogens and the green is Nobel Gases. I will talk about them later. :D
