Basic objective of this lecture is to present Alkali Metals and the Alkaline Earth metals. The Group 1 elements have a specific family name—alkali metals. Each alkaline earth metal is denser and harder and has a higher melting point than the alkali metal in the same period. Alkaline earth metals are reactive, but not as reactive as the alkali metals. Here also briefly explain Groups 1 and 2 are always found in nature combined with other elements and why they’re called active metals because of their readiness to form new substances with other elements.
