Is Ca2+ Ionic or Covalent

Calcium :; electronic configuration = 2,8,8,2 after losing two electrons it can acquire noble gas configuration which means stable configuration thus forms anion of calcium which is Ca2+ . So we can say calcium can form ionic bond.

Why CaO is an ionic compound?

Calcium oxide is considered an ionic compound as it comprises a metal (calcium) and a nonmetal (oxygen). … Since, the loss of electrons by one and gain by another atom form an ionic bond between two elements, calcium oxide (CaO) is also ionic.
