CALCIUM ION Meaning and
Definition
-
Calcium ion is a term used in chemistry and biochemistry to describe the positively charged form of calcium (Ca2+) atom. Calcium is a chemical element that belongs to the alkaline earth metals group of the periodic table, with an atomic number of 20 and a corresponding atomic mass of 40.08 atomic mass units.
When a calcium atom loses two electrons, it forms a calcium ion with a positive charge of +2. This cationic form of calcium is highly reactive and plays a crucial role in numerous biological processes, especially in living organisms. Calcium ions are involved in various physiological functions such as muscle contraction, nerve transmission, bone formation, blood clotting, and cell signaling.
In aqueous solutions, calcium ions exist as hydrated ions, meaning they are surrounded by water molecules. The hydration of calcium ions greatly influences their solubility and reactivity. The presence of calcium ions in water is important for maintaining water hardness and influencing the taste and quality of water.
Calcium ions are also important for cellular signaling processes. They act as second messengers, transmitting signals within cells by binding to specific calcium-binding proteins such as calmodulin. This binding triggers a cascade of intracellular events that regulate various cell functions, including gene expression, enzyme activity, and hormone secretion.
In summary, calcium ions are the positively charged form of calcium atoms that play a vital role in numerous biological processes, ranging from muscle contraction to cellular signaling.

Etymology of CALCIUM ION
The word "calcium" comes from the Latin word "calx", which means lime or limestone. The metal calcium was named after this term due to its association with lime and limestone. The suffix "-ium" is a standard naming convention used in chemistry to indicate an element.
The term "ion" originates from the Greek word "ion", which means "going" or "wandering". It was used by Michael Faraday in 1834 to describe electrically charged atoms or molecules that move or migrate in aqueous solutions. Hence, "calcium ion" refers to the electrically charged form of the calcium element.
