Answer:
see explanation
Explanation:
The process of ionization to produce cations is endothermic. For formation of Ca⁺² two ionization steps need be illustrated as follows...
1st ionization step: Ca° + 590Kj => Ca⁺ + e⁻
2nd ionization step: Ca⁺ + 1151Kj => Ca⁺² + e⁻

Net Ionization Rxn: Ca° + 1741Kj => Ca⁺² + 2e⁻
What occurs is they neutralize both acid and base characteristics/features, usually producing a salt.
