Grade LevelHigh School
This activity is meant as a supplement to a lesson on electronegativity and bonding. It is intended to provide students with an opportunity to analyze how the electronegativity of different atoms can change the properties of bonds and resultant compounds. Through the Bite, students will come to appreciate how their knowledge has applications in the field of cancer research.
Upon completion of this lesson, students will be able to:
- compare the electronegativity values of different atoms.
- explain how nonpolar covalent, polar covalent, and ionic bonds can be modeled on a continuum characterized by electronegativity differences between the bonded atoms.
- describe how the electronegativity value of an atom can affect the properties of a bond and the resultant compounds.

"I always find it exciting to get kids to work from data from scientific research. I think it's wonderful for them to realize that what might seem like "information" to learn are powerful concepts with which, for example, could help design new molecules that will allow cancer research to progress."
– Barbara Scapellato, scientific high school of the IISS Paciolo-D'Annunzio di Fidenza, Fidenza, Italy/i>
“This lesson was perfect to let students know that electronegativity is not just a theme to keep them busy, but that it is something that occurs in nature and that can be used in positive ways to benefit mankind."
– Rolando Zamora, American Institute of Monterrey in San Pedro Garza García, Mexico
"A great opportunity for authentic learning!"
