Periodic TableHard
Question
The statements that is / are true for the long form of the periodle is / are :
Options
A.It helps to predict the stable valency states of the elements
B.It reflects the sequence of filling the electrons in the order of sub-energy level s, p, d and f
C.It reflects tends in physical and chemical properties of the elements
D.It helps to predict the relative ionicity of the bond between any two elements
Solution
These are the advantages of long form of periodic table. (b) Can′t taken as correct choice, because on the basis of E.C., we can predict the possible oxidation states but not most stable one.
