Calcium oxide (CaO) forms when an atom of calcium loses two electrons, giving it a +2 charge, and an atom of oxygen picks up two electrons, giving it a -2 charge.

What is calcium oxide?

A. An element
B. A covalently bonded compound
C. An ionically bonded compound

Asked by MaryaHufstedler504

Answer (2)

c- an ionically bonded compound, since it forms by Ca losing electrons and O gaing electrons it is an ionic compound. an ionic compound is a compound formed by different charged elements that lose or gain electrons, hope that helped :)

Calcium oxide (CaO) is an ionically bonded compound formed from the transfer of electrons between calcium and oxygen. Calcium loses two electrons becoming Ca²+, while oxygen gains two electrons becoming O²-. Therefore, the correct answer is C. An ionically bonded compound.
