Chapter 6: Electronic Structure of Atoms
To understand the electronic structure of atoms, one must understand the nature of electromagnetic radiation. The distance between corresponding points on adjacent waves is the wavelength ().

Classifying Electrolytes Electrolytes are substances which, when dissolved in water, break up into cations (pluscharged ions) and anions (minus-charged ions). We say they ionize. Strong electrolytes ionize completely (100%), while weak electrolytes ionize
