Group 2 - Alkaline Earth Metals

The video tutorial explores the properties and reactions of alkaline earth metals, focusing on magnesium and calcium. It discusses their reactions with oxygen and water, highlighting the formation of oxides and hydroxides. The tutorial also compares the reactivity trends within the group, noting that reactivity increases down the group. Magnesium reacts with oxygen to form magnesium oxide and with steam to produce hydrogen gas. Calcium reacts with oxygen to form calcium oxide and with cold water to produce calcium hydroxide and hydrogen gas. The video emphasizes the importance of understanding these reactions and their implications.
