Question

Identify the group 16 $\left(VIA\right)$ elements which is the most electronegative ?

• A. $O$
• B. $S$
• C. $Te$
• D. $Po$

Answer 1

The correct option is A $O$

All theses O,S,Se,Te,Po are group 16 elements from top to bottom.As we move from top to bottom in a group as the size increses the electronegativity decreases.So most electronegative element is Oxygen
The order of electronegativity is O>S >Se>Te.Po.
Hence option A is correct.
