Calculating Formula Weight and Molecular Weight
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
In this interactive object, learners calculate formula and molecular weights by working through five examples and two problems.
Ions are electrically charged particles obtained from an atom or from a chemically bonded group of atoms by adding or removing electrons. Eight examples illustrate the number of protons, neutrons, and electrons in positive ions (cations) and in negative ions (anions).
In this animated and interactive object, learners examine the inverse proportionality of wavelength and frequency and their relationship to the speed of light.
