Title: electronegativity Post by: dbos on Mar 26, 2014 What determines a higher or lower electronegativity?
Title: Re: electronegativity Post by: padre on Mar 26, 2014 Electronegativity increases as you move across a period because the atoms gain more electrons which makes them closer to achieving the ideal octet. Along with gaining electons they gain protons that pull the shells/orbitals closer together thus demanding more energy to have an electron pulled away.
