The Lewis representation above depicts a reaction between a halogen (blue) and a main-group element from group (7A + (red). In this representation, each Y atom needs 1 electron(s) to complete its octet, and gains these electrons by forming bond(s) with atoms of X . There are unshared electron pair(s) and bonding electron pair(s) in the product molecule. The bonds in the product are Submit Answer Retry Entire Group 9 more group attempts remaining Previous Next Email Instructor Save and Exit Cengage Learning | Cengage Technical Support
