Atomic Structure Atomic structure of an atom based on energy relative to size of an electron can be measured with Einstein?s formula of e=mc2. However, energy of an electron within an atom based on how long a wavelength takes to pass can be determined with the formula of constant= wavelength x frequency. Electromagnetic Radiation is described with wavelike energy with both magnetic and electrical properties. Waves of electrons (atoms) are within radiation additionally wave measurements can be made with the wavelength, frequency, and the speed of light (constant). Wavelength= Indicated with lambda, described as the length of a wave from one crest to another. Frequency= Measured in Hz (1/s), the number of waves that pass per second

1 THE MOST BASIC CHEMISTRY REVIEW This review is intended to remind you of the BASICS that you learned. It is NOT COMPLETE. CLASSIFYING MATTER elements, compounds, or mixtures PROPERTIES OF MATTER INTensive?a property that doesn?t depend on amount (ex- boiling point) Extensive?a property that does depend on amount (ex- mass or volume) density ? amount of matter in a given volume Density = mass volume units: g/cm3 for solids, g/mL for liquids density column Example A piece of wood that measures 3.0 cm by 6.0 cm by 4.0 cm has a mass of 80.0 grams. What is the density of the wood? Would the piece of wood float in water? If the wood were cut into three pieces would it have the same density?

Electromagnetic Spectrum - various forms of light, consisting of oscillating electric and magnetic fields ? ? ? The Wave Nature of Light ? Wavelength - distance between corresponding points on a wave Amplitude - height of the wave from equilibrium position Frequency - number of cycles of a wave passing a certain point per second (measured in Hz) **note: amplitude corresponds with brightness, wavelength and frequency correspond with color ? Speed of light ( c ) : c = lamda x v = wavelength x frequency ? The Particulate Nature of Light

Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 05 November 2012 Jespersen, Brady & Hyslop Chapter 8 The Quantum Mechanical Atom Quantum Mechanics Ch. 8.1 The physics that describes objects with wave-particle duality is called quantum mechanics or quantum theory. In the late 1800?s, scientists discovered that electrons acted like tiny charged particles in some experiments and waves in others. Quantum mechanics accurately describes the structure and reactivity of atoms and molecules. Electromagnetic Radiation Ch. 8.1 Energy can be transferred as heat or as light. Electromagnetic radiation can be carried energy through space in the form of electromagnetic waves.

* Chapter 7 Periodic Properties of the Elements John D. Bookstaver St. Charles Community College Cottleville, MO Lecture Presentation Development of Periodic Table Dmitri Mendeleev and Lothar Meyer independently came to the same conclusion about how elements should be grouped. Development of Periodic Table Mendeleev, for instance, predicted the discovery of germanium (which he called eka-silicon) as an element with an atomic weight between that of zinc and arsenic, but with chemical properties similar to those of silicon. Periodic Trends In this chapter, we will rationalize observed trends in Sizes of atoms and ions. Ionization energy. Electron affinity. Effective Nuclear Charge
