Why is calcium oxide an ionic bond?

Answer 1

Calcium hydroxide has groups of covalently bonded atoms that have either lost or gained electrons. It is an ion made up of two or more atoms that are covalently bonded and that act like a single ion.

~Ayanna~ Your answer doesn't answer the question. ****************** This answer will: The covalent part is between the O-H of the hydroxide. In this instance, O and H always bond covalently. Calcium's bond with the OH, which is a separate subject, is ionic, as in Ca ++ : (OH -) x 2 Almost all compounds involving metals are ionic, so this is typical. That should clear it up

Answer 2

It is possible for calcium hydroxide, Ca (OH)₂, to have both ionic and covalent bonds is because there are ions called polyatomic ions and those ions are groups of covalently bonded atoms that have either lost or gained electrons.

Answer 3

Because, the calcium atoms bind with the oxygen atoms. (Ionic bond - metal and non metal)

Then the Carbon atom binds to the oxygen atoms, which is a covalent bond (non metal - non metal)

Hence both ionic and covalent bonds included.

Answer 4

Calcium oxide is an ionic compound because it is composed of a metal (calcium) and a non-metal (oxygen) bonded together through the transfer of electrons. In this case, calcium loses two electrons to oxygen, forming Ca2+ cations and O2- anions, which then attract each other through electrostatic forces to form the ionic bond.

Answer 5

Because its made of Calcium and Oxygen (Gas and Metal) which qualifies as Ionic bond.
