Reactivity Series: Comparing the Reactivity of Group 1 and Group 2 Metals

The video tutorial explores the reactivity of four metals: sodium, potassium, magnesium, and calcium. It demonstrates experiments to compare their reactivity using water and hydrochloric acid. The tutorial explains atomic structure, focusing on electron shells and metallic bonds, and discusses reactivity trends in the periodic table. It highlights that Group 1 metals are more reactive than Group 2 metals, and reactivity increases down the groups. Practical applications of reactivity, such as tin electroplating in food cans, are also covered.

How do the outer electrons of Group 2 metals affect their reactivity?

What role do positive hydrogen ions play in the reaction with hydrochloric acid?

What is the order of reactivity for the four metals tested?

Why is tin used in the manufacture of food cans?
