Chapter 7 Electrons in Atoms. Properties of Electrons Electrons display both particle properties and wave properties. Electrons were discovered by JJ.
Electromagnetic Radiation Radiant energy that exhibits wavelength- like behavior and travels through space at the speed of light in a vacuum. Example:
Chapter 11 - Arrangement of Electrons in Atoms The “Puzzle” of the nucleus: Protons and electrons are attracted to each other because of opposite charges.

Atomic Models Plum Pudding Model (1900s) Lord Kelvin/JJ Thomson—no nucleus! Rutherford’s Model (early 1910s) Rutherford—atom has a nucleus! Rutherford.
