Question

Covalence of central atom is maximum in

Answer 1

Answer:

Answer. 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. . Thus an element can show a maximum covalency equal to its group number e.g. chlorine shows maximum covalency of seven

Answer 2

Explanation:

the below information may be helpful to you

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. . Thus an element can show a maximum covalency equal to its group number e.g. chlorine shows maximum covalency of seven.

ANSWER

First, note that covalency = number of bonds formed.
