What element in the same group as polonium has a lesser electronegativity?

Question

What element in the same group as polonium has a lesser electronegativity?

1.  oxygen
2.  selenium
3.  sulfur
4.  tellurium
5.  none of the above

Answer 1

In order to answer this question you must recall the periodic trend for electronegativity.

Electronegativity decreases from top to bottom, so look for an element lower in the group. There are no elements lower than Po in the vertical group, so the answer must be "none of the above"
