Calcium oxide (CaO) consists of calcium (Ca) and oxygen (O). Calcium, a group 2 element, has 2 valence electrons, while oxygen, a group 16 element, has 6 valence electrons. Therefore, in total, CaO has 2 (from Ca) + 6 (from O) = 8 valence electrons.

How many electrons in calcium oxide molecule (CaO)?

First, calcium oxide is an ionic compound and so does not form molecules. In one formula unit (ionic equivalent of a molecule) of calcium oxide there is 1 oxygen (8 protons) atom and 1 calcium atom (20 protons) for a total of 28.


How many electrons does one Adam of calcium donate to one atom of oxygen during the formation of the compound CaO?

In the formation of calcium oxide (CaO), one atom of calcium donates two electrons to one atom of oxygen. Calcium, which is an alkaline earth metal, has two valence electrons and readily loses them to achieve a stable electron configuration. Oxygen, a nonmetal, requires two electrons to complete its valence shell, thus forming the ionic compound CaO.

Depends on what you mean by number of electrons. Calcium has 20 electrons and oxygen has 8 electrons for a total of 28 electrons. But if you mean how many VALENCE electrons, then the calcium has 2 and the O has 6 for a total of 8 valence electrons.
