Alkali metal

11 - Sodium

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.

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

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

An enriching Sodium design. Sodium is a chemical element with symbol Na (from Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atom—the Na+ cation.
