Rutherford Model Know where the protons and neutrons are, but where are the electrons? If opposite charges attract, why do the electrons not fall into the nucleus?

EMR Electromagnetic radiation (EMR) is a form of energy that exhibits wavelike behavior as it travels through space. Packets of energy (photons) that travel as waves

Structure of a Wave

Energy of a wave Low frequency/large wavelength = low energy High frequency/small wavelength = high energy

Electromagnetic Spectrum Electromagnetic radiation: Includes radio waves, microwaves, x-rays, and visible light Spectrum: the range of wavelengths & frequencies of electromagnetic radiation

Electromagnetic Spectrum Visible Spectrum: A beam of light can be separated into different wavelengths of light when passed through a prism

Which colors of light are high energy? Which colors of light are low energy? http://www.lcse.umn.edu/specs/labs/images/spectrum.gif

Bright-Line Spectra When an element is excited (or energy is applied) the element emits light. When this light is passed through a prism, a unique spectra, called an atomic line spectra, is visible
