Alkali metal

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.

Sodium. Sodium is a chemical element with the symbol Na (from Latin: natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal and is a member of the alkali metals; its only stable isotope is 23Na.

What is the difference between Alkali Metals and Alkaline Earth Metals? Each alkali metal has a single electron; each alkaline earth metal has two electrons

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
