Tag: Group 2

With an atomic number of 20, calcium (Ca) is the fifth most abundant element in the Earth's crust, but did you know its position on the periodic table defines its chemical behavior? If you want to know in which group will you find calcium, the answer is Group 2, a classification that explains its high reactivity and metallic properties.

As the fifth most abundant element in Earth's crust, calcium is a highly familiar element, though its classification is a specific chemical matter. It is best classified as an alkaline earth metal, distinguishing it from other types of elements due to its distinct chemical and physical characteristics. This classification is based on its position within the periodic table and its reactive nature.
