what is the covalency of Xenon in third excited state
Answers
Answer:
Maximum Covalency
Elements which have vacant d-orbital can expand their octet by transferring electrons, which arise after unpairing, to these vacant d-orbital e.g. in sulphur.
In excited state sulphur has six unpaired electrons and shows a valency of six e.g. in SF
6
. Thus an element can show a maximum covalency equal to its group number e.g. chlorine shows maximum covalency of seven.
