What characteristics are shared by calcium and magnesium?

Question

Serenity Allen · Accepted Answer

They are both #"alkaline earth metals........"# Got a Periodic Table handy? The metals lie in Period 2 and Period 3 of Group 2 of the Periodic Table. What are their atomic numbers? The elements are thus #"alkaline earth metals"# with (necessarily) 2 valence electrons.

Peyton Adams · Answer

undefined Both calcium and magnesium are alkaline earth metals in Group 2 of the periodic table, with two electrons in their outermost shell. They are both essential for a number of biological processes and are frequently found in mineral deposits in the crust of the Earth. Furthermore, they both form divalent cations with an oxidation state of +2, which are called Ca²⁺ and Mg²⁺, respectively.

Noah Aldrich · Answer

undefined Calcium and magnesium are both alkaline earth metals in the periodic table. They share several characteristics:

1. Both calcium and magnesium have two valence electrons in their outermost electron shell.
2. They are both relatively reactive metals.
3. Both elements form divalent cations (Ca²⁺ and Mg²⁺) when they lose electrons.
4. Calcium and magnesium are essential for biological processes in living organisms.
5. They are both commonly found in mineral deposits and in the Earth's crust.
6. Both elements are used in various industrial applications, such as in the production of alloys and as additives in steel manufacturing.
7. Calcium and magnesium ions play crucial roles in water hardness and are commonly found in groundwater sources.
