Question

Alkaline earth metals are involved in two key diagonal relationships in the periodic table.(a) Give the two pairs of elements in these diagonal relationships.

Answer 1

Two alkaline earth metals; Be and Mg exhibit a diagonal relationship. The pair of elements are Be-Al and Mg-Li is Be-Al and Mg-Li.

Six elements make up the majority of alkaline earth metals (Group 2): beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). Compared to the elements in Group 1, this group typically contains smooth, silver metals with a less metallic character. Heavy metals like Ca, Sr, Ba, and Ra are equally as reactive as Alkali Metals Group 1 despite sharing many characteristics with that group. All elements found in alkaline earth metals contain two electrons in their valence shells, giving them an oxidation state of +2. This makes it possible for metals to shed electrons with ease, allowing them to create compounds with more stable ionic connections.
