Difference Between Calcium Atom and Calcium Ion

The calcium atom and the calcium ion differ in their electrical charge and chemical behavior.

- The calcium atom is a neutral particle with an equal number of protons and electrons. It is represented by the chemical symbol Ca. The atomic number of calcium is 20, and its atomic mass is approximately 40.08 atomic mass units (amu).

- On the other hand, the calcium ion is a positively charged particle that forms when a calcium atom loses two electrons. It is represented as Ca^2+. The loss of electrons gives the calcium ion a net positive charge, making it a cation.

The difference in charge between the calcium atom and the calcium ion leads to distinct chemical behaviors. For example, the calcium ion is more reactive and participates in various chemical reactions due to its positive charge
