How do the chemical reactivities of elements within the alkali metals group and the alkaline earth metals group compare, and what factors contribute to these differences? write them in a big, short complete sentence with differences between them

Answer 1

The alkali metals group (Group 1) is more reactive than the alkaline earth metals group (Group 2) due to their having a single valence electron that is easily lost to form positive ions, resulting in lower ionization energy and greater reactivity, while the alkaline earth metals, with two valence electrons, require more energy to remove one electron and therefore react less vigorously; additionally, the presence of a filled outer electron shell in alkaline earth metals contributes to their comparatively lower reactivity.
