In the following table, six elements A, B, C, D, E and F (here letters are not the usual symbols of the elements) of the modern periodic table with their atomic numbers are given.

If B combines with F, what would be the formula of the compound formed?

Text Solution

Verified by Experts

B with atomic number 11 will have electronic configuratiomn (2, 8, 1). It will lose one electron . F with atomic number 17 will have electronic configuration
(2,8,7) . It will gain one electron. ltbr. :: Compound formed will have formula BF.
