Atom A,B and C occur in the same period ...

Atom A,B and C occur in the same period and have one, six and seven valence electron respectively.
(a) Will the bonds between B and C be predominantly ionic or covalent ?
(b) Will the bond between A and B be predominantly ionic or covalent ?
(c ) Write he electronic structure of the compound between B and C

Text Solution

Verified by Experts

(a) The bond between atoms B and C will be predominantly covalent as the difference of electronegatively is expected to be very small.
(b) The bond between A and B will be predominantly ionic due to large difference in the electronegativity values.
(c ) The electronic structure of compound formed between B and C (C-B-C) is `overset(* *)underset(* *)(":"C)overset(* *)underset(* *)(":"B":")overset(* *)underset(* *)(C":")`
