Question

The valency of group 16 elements is 2 ( write the true or false and false reason )​

Answer 1

Answer:

true.

Explanation:

The group 16 consists of oxygen (O), Sulfur (S), Selenium (Se), tellurium (Te) and Polonium (Po). The general electronic configuration of this group elements is ns2np4. So the number of valence electrons is 6. So the valency could be from 2−6 (except for O). Because oxygen doesn't have a d-orbital to occupy more than two-electron. However, the common valency of this group is 2. 

Answer 2

Answer:

Here is your answer :

True

Group 16 elements have 6 valence electrons, meaning that they require two more electrons to complete a stable electron octet. They still have relatively large electron affinities and are rather reactive, forming ions with a -2 charge.
