Jul 2, 2021 · All elements in Group 2 (also called alkali earth metals) have two electrons in their outermost principal quantum shell. All Group 2 metals can form ionic compounds in which they donate these two outermost electrons (so they act as reducing agents) to become an ion with +2 charge (so they themselves become oxidised) Going down the group, the ...

Feb 5, 2024 · Reactions of the oxides of group 2 elements with water. Group 2 ionic oxides react with water to form hydroxides. The ionic oxides are basic as the oxide ions accept protons to become hydroxide ions in this reaction (acting as a bronsted lowry base) MgO (s) + H2O (l) Mg(OH)2 (s) pH 9.
Four of the six group 2 elements—magnesium (Mg), calcium (Ca), strontium (Sr), and barium (Ba)—were first isolated in the early 19th century by Sir Humphry Davy, using a technique similar to the one he used to obtain the first alkali metals.

Group 2 elements, known as alkaline-earth metals, include Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). These elements are s-block elements as their outer electrons are in s-orbitals. Alkaline-earth metals have two electrons in their outermost s orbital.
