dharavsolanki said:So you have found the molecular masses of the oxide. Good.
Now use the fact that molecular mass of Oxygen atom is 16. What possibilities does it leave for the molecular mass of the other element?
Show some approximate calculations, and we'll proceed further!
The valencies of elements in 3 oxides can be determined by analyzing the molecular formula of each oxide and using the rules of valency to determine the oxidation states of the elements present.
The rules of valency state that the valency of an element is equal to the number of electrons it gains, loses, or shares in order to achieve a stable outer shell. The valency can be determined by looking at the group number of the element in the periodic table.
Yes, the valencies of elements can vary in different oxides. This is because the valency of an element is dependent on its oxidation state, which can change depending on the other elements it is bonded with in a compound.
The periodic table can be used to find the valencies of elements in 3 oxides by looking at the group number of the element. The group number indicates the number of valence electrons an element has, and this can help determine its valency.
Yes, there are some exceptions to the rules of valency. For example, transition metals can have multiple valencies, and some elements can have variable valencies depending on the compound they are in. It is important to consider the overall charge of the compound when determining valencies.
