Question

Using the periodic table only, arrange the elements in each set in order of increasing EN:

Answer 1

Oxygen to sulfur is less polar than comparable bonds to oxygen because sulfur is less electronegative than oxygen.

In groups, electronegativity rises from bottom to top; across periods, it rises from left to right. In groups, electronegativity rises from bottom to top; across periods, it rises from left to right. Fluorine is the element with the greatest electronegative charge, whereas francium has a very low electronegative charge. Within a set of elements, electronegativity values drop from top to bottom. Moving from left to right along a period improves electronegativity. This is caused by a decrease in atomic size and a rise in nuclear charge, which allows a shared electron pair to be more attracted to one another.
