Valence of Oxides:

The valence of an element in an oxide refers to the number of electrons that the element gains or loses when it forms the oxide. It is also known as the oxidation state of the element in the oxide. Here are the valences of the given oxides:

1. Cs2O: The valence of Cs (cesium) in Cs2O is +1, and the valence of oxygen (O) is -2. This can be determined by
