Exemplar Problems

Problem 7 : Compare and contrast the properties of alkali metals (Group 1) and alkaline earth metals (Group 2) in terms of reactivity, ionization energy, and atomic size.

Solution :

• Alkali Metals (Group 1): Highly reactive, low ionization energy, and low melting and boiling points.
• Alkaline Earth Metals (Group 2): Reactive but less so than alkali metals, higher ionization energy, and higher melting and boiling points.
