1 Notes from Atoms Unit September 2, 2016
**Take notes on slides: #24-the last slide, all other slides are review from yesterday, but please go through all of them.

2 Hydrogen is an odd ball. Copyright © 2010 Ryan P. Murphy

3 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

4 Hydrogen is an odd ball. It’s grouped with the alkali metals because it has a similar outer shell electron configuration as they do. It’s not metal? Copyright © 2010 Ryan P. Murphy

38 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

39 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

40 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. “Not the Noble Gases however.” Copyright © 2010 Ryan P. Murphy

41 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. “Not the Noble Gases however.” “They’re wicked different.” Copyright © 2010 Ryan P. Murphy
