Jun 30, 2023 · The metal was discovered and isolated in 1911 by Marie Curie. The elements in the group include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
Group 2 elements are commonly known as alkali earth metals as their oxides produce basic solutions when dissolved in water. i) State how many electrons a Group 2 element has in its outermost shell. [1] ii) State how a Group 2 element forms an ionic bond with non-metals. [1]
Jul 12, 2023 · 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.
