An atom of which element has the greatest attraction for the electrons in a bond with a hydrogen atom?
(1) chlorine (3) silicon
(2) phosphorus (4) sulfur



Answer :

The question can be changed into a new form:
Which element has the most negative electron affinity, or attraction for electrons? halogens have the highest electron affinities, and thus are more attracted to the electrons in the Hydrogen atom than any element in their respective periods.
In this case all the following choices are in the same period, thus Cl or Chlorine is the answer as it is a halogen.

The atom with the greatest attraction for the electrons in a bond with an hydrogen atom is Chlorine (Cl).

Chlorine (Cl)

Chlorine (Cl) is a chemical element with an atomic number of 17. It is the second element in the group 8 element also known as the halogens.

Halogens are the most reactive non-metals on the periodic table. Therefore amongst the elements listed above, Chlorine has the greatest attraction for the electrons in a bond with an hydrogen atom.
