Hydrogen is an odd ball. Copyright © 2010 Ryan P. Murphy
Hydrogen is an odd ball. It’s grouped with the alkali metals because it has a similar outer shell electron configuration as they do. Copyright © 2010 Ryan P. Murphy

Electronegativity is a measure of the attraction of an atom for the electrons in a chemical bond. Copyright © 2010 Ryan P. Murphy
Electronegativity is a measure of the attraction of an atom for the electrons in a chemical bond. The higher the electronegativity of an atom, the greater its attraction for bonding electrons. Copyright © 2010 Ryan P. Murphy
Electronegativity is a measure of the attraction of an atom for the electrons in a chemical bond. The higher the electronegativity of an atom, the greater its attraction for bonding electrons. “Those elements attract electrons like wicked.” Copyright © 2010 Ryan P. Murphy
