Alkaline Earth Metals Overview

This video from Moomoomath and Science introduces the alkaline earth metals, which are located in group 2 of the periodic table. These metals include beryllium, magnesium, calcium, strontium, and radium. They share properties such as low density, being silver and soft, and are ductile and malleable. Alkaline earth metals react with halogens and water, but are less reactive than alkali metals due to having two electrons in their outer shell. They are typically found in compound form in nature. The video also highlights common uses, such as strontium in fireworks, calcium for bones, magnesium in antacids, and beryllium in light bulbs. The video concludes with a summary and encourages viewers to subscribe for more content.
