Question

How do you determine which atom within a group has the greatest attraction for the electrons in a chemical bond?

For example:

hydrogen

oxygen

silicon

sulfer

Answer 1

for the above group ans. is oxygen.

Explanation:

the first thing to determine the atom in a group having most attraction for the electrons in a chemical bond is its `ELECTRONEGATIVITY.`
in the above group oxygen is most electronegative,so it has the most attraction for the electrons in chemical bonds.
but in different cases there are other things which determines this attraction i.e i).the presence of vacant subshells,ii) number of electrons present in the valence shell,iii)shielding effect,iv)penetration of different orbitals v)repulsion between the electrons present in the valence shells.
