PART B CONCEPT REVIEW CHEMICAL BONDS

Chapter 6 Review: Chemical Bonding Flashcards | Quizlet
A hydrogen bond is a dipole - dipole attraction between a partially positive hydrogen atom and the unshared electron pair of a strongly electronegative atom such as O, N, or F. Unlike ionic or covalent bonds, in which electrons are given up or shared, the hydrogen bond is a weaker attraction.[PDF]

4.4: Polar and Non-polar Covalent Bonds - Chemistry LibreTexts
This is a nonpolar covalent bond. (b) The fluorine atom attracts the electrons in the bond more than the hydrogen atom does, leading to an imbalance in the electron distribution. This is a polar covalent bond. Any covalent bond between atoms of different elements is a polar bond[PDF]

The placekicker’s chemical potential energy changes into mechanical energy in the legs, which changes into kinetic and potential energy in the football. 9. Chemical potential energy transforms into kinetic energy, which changes to thermal energy as a result of friction between the runner and the ground. 10. Chemical potential energy is changed into ther-
