Kalsiumatomeilla
Kalsiumatomeilla refers to calcium atoms. Calcium is a chemical element with the symbol Ca and atomic number 20. It is a soft, silvery-white metal belonging to the alkaline earth metals group. Calcium is essential for living organisms, particularly in cell structure, signaling, and as a component of bones and teeth. In chemistry, calcium atoms readily lose two electrons to form a positive ion, Ca2+. This ionic nature makes calcium a highly reactive metal.
Calcium is abundant in the Earth's crust, found in minerals like limestone, gypsum, and fluorite. Its discovery
The electronic configuration of a calcium atom is [Ar] 4s2, indicating that its outermost electrons are in
