how did Frankland's concept of "combining power" contribute to the development of valency?

Oct 15, 2022 ... Answer: (a) Element A forms an oxide A 2 O 5 . Crossing the valencies, we can see that the valency of O (oxide) is −2 and that of element A is 5. When element Z combines with fluorine, then its fluoride is formed. Now, valency of element Z is 6 and the valency of element fluorine, F, is 1. Nov 26, 2020 ... ... (valency).
