CHEM 111 1nd Edition Lecture 6 Outline of Last Lecture I. Symbols of NuclidesII. Periodic TableIII. The Molea. Moles as Conversion Factors b. Molecular mass/ formula massOutline of Current Lecture II. Gravitational and electrostatic forces Current LectureGravitational force between two objects:These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Electrostatic force between two objects:F= forceG= proportionality constantR2= distance between centers of objectsM1, M2 = masses of two objectsQ1, Q2 = charges of two objects Just like there’s potential energy between the skater and the earth, there’s potential energy between charged particlesPotential energy depends on the relationship between two objectsEX: The electron of a hydrogen atom is taken away completely from the atom (That is, the electron and the proton are so far apart that they’re not attracted and don’t influence each other.)o The potential energy will increase while the kinetic energy will decreaseWhen potential energy= 0 , kinetic energy will be less than
