2 H+ + Ý: The Lewis representation above depicts a reaction between hydrogen (blue) and a main. group element from group (red) In this representation, each Y atom needs electron(s) to complete its octet, and gains these electrons by forming bond(s) with atoms of H. unshared electron pair(s) and bonding electron pair(s) in the product There are molecule. The bonds in the product are

For each bond, show the direction of polarity by selecting the correct partial charges. Si-S – – Si-CI – CI-S- The most polar bond is
