Atoms of eight elements A, B, C, D, E, F...

Atoms of eight elements A, B, C, D, E, F, G and H have the same number of electronic shells but are different number of electrons in their outermost shells. It was found that elements A and G combine to form an ionic compound which can also be extracted from sea water. Oxides of the elements A and B are basic in nature while those of E and F are acidic. The oxide of elements D is almost neutral.
Which two elements amongst these are likely to be the non-metals ?

A

A and C are likely to be non-metals.

B

G and H are likely to be non-metals.

C

C and D are likely to be non-metals.

D

E and F are likely to be non-metals.

Text Solution

Verified by Experts
