The element located in period 4 and group 2 of the periodic table is called Calcium, and its chemical symbol is Ca.
Calcium is an essential alkaline earth metal that plays a critical role in various biological and physical processes. Being in group 2, it signifies that Calcium has two electrons in its outermost shell, which it readily loses during chemical reactions, making it a reactive element. This reactivity is particularly evident when Calcium reacts with water, forming calcium hydroxide and releasing hydrogen gas.
In everyday life, Calcium is well-known for its importance in bone health, as it is a major component of bones and teeth. Additionally, it serves vital functions in muscle contractions, blood clotting, and nerve signaling.
