WebThe most important property that differentiates non-metals from metals is their low or non-existent electrical conductivity. Electronegativities are high in non-metals. This means that non-metal atoms have a significant tendency to attract more electrons than they would otherwise have. Electronegativities in non-metals are high. http://chemed.chem.purdue.edu/demos/demosheets/7.3.html
