Elements A, B and c belong to the same period in the long form of the periodic table. nature of the The oxides of A, B and c is amphoteric, basic and acidic respectively . The correct order of the atomic number of these elements is :

A                        B                 CAmphoteric        Basic            AcidicOn moving left to right along the same period, acidic nature of oxide increases. Basically, basic nature of oxides changes from amphoteric to acidic on moving along a period.B < A< C in atomic number.
