Question

Total number of vacant orbitals in the valence shell of bromine atom when it forms maximum covalent bonds
A.9. B.2. C.3. D.5

Answer 1

Answer:

Explanation:

THIS CAN BE SOLVED BY CONFIGURATION

WRITE CONFIGURATION OF BROMINE BY NEAREST NOBLE GAS

FOR THAT YOU NEED ATOMIC NO. OF BROMINE

WHICH IS 35

MEANS NEAREST NOBLE GAS IS ARGON

AR 4s2 3d10 4p5

here for excitation there are 4d and 4f

for maximum covalency excitation should be done

after excitation you can see only 1 orbital is empty that is 4f
