Question

write common radicals with their valencies
!???

Shubhangini Kumari · Accepted Answer

The valencies of radicals are counted as the net charge
on the radical
For positive radicals the valencies are equal to net +ve charge
on the species, while for negative radicals the valencies are equal
to net -ve charge on the species Some common examples are:
