Answer 2

CdO, also known as cadmium oxide, is a chemical compound composed of the elements cadmium (Cd) and oxygen (O). In order to determine the valency of CdO, we need to consider the oxidation state of each element.

Cadmium (Cd) is a transition metal that can exhibit different oxidation states. The most common oxidation state for cadmium is +2, where it loses two electrons to form a Cd2+ ion. Oxygen (O), on the other hand, typically has an oxidation state of -2, where it gains two electrons to form an O2- ion.

To determine the valency of CdO, we need to balance the charges of the ions. Since the Cd2+ ion has a charge of +2 and the O2- ion has a charge of -2, we can see that one Cd2+ ion can combine with one O2- ion to form a neutral compound, CdO.

Therefore, the valency of CdO is 2 for cadmium (Cd) and -2 for oxygen (O). This means that one cadmium atom can combine with one oxygen atom to form CdO.

Please note that the valency of an element can vary depending on the compound it is part of and the specific chemical reaction. The valency mentioned here is specific to the compound CdO.

I hope this helps! Let me know if you have any further questions.
