Atom of which of the following elements has the greatest ability to attract electrons

HELLO!

 

The tendency to attract electrons is known as Electronegativity.

 

In the Modern Periodic table, the Trend of Electronegativity is:

Now, smaller the size of the atom, greater is the nuclear pull on the valence electrons, due to which, the atom of the element can easily attract electrons towards itself. In the above four options, size of Sulphur atom is the smallest. Moreover, it lies in a better position than the other three elements to show more Electronegativity.
