Answer:

Explanation:

Calcium has a chemical symbol of Ca and has an atomic number of 20. This means that a neutral calcium ion will have 20 protons and 20 electrons. As part of Group 2 (alkaline earth metals), a calcium ion will be formed by ejecting 2 electrons from the neutral Ca atom. In chemical equation,

                           

                                          Ca --> Ca²⁺ + 2e⁻
