Unformatted text preview: Atomic Bonding Chapter 2 Matter is composed of Elements 92 naturally occurring Atomic Number # of protons Mass Number # of protons + # of neutrons Atomic Weight Average Grams/mole Mole # of atoms in 12 grams of Carbon12 Avogadros Number 6.022*10^23 lb mole used in English calculations # of atoms in 12 lb m of Carbon12 What kind of calculations can you do using the definition of a mole? Bohr Model of the Atom Both Bohr and Schrodinger knew that matter can be thought of as either a particle or a wave Bohr chose to think of electrons as particles with wave characteristics This approach is usually more intuitively easy to understand Quantum Mechanics What the Bohr model cant explain is that only certain energy states are possible for an electron Schrodinger thought of the electron as a wave Consider a slinky Only certain wavelengths are possible There are nodes that can not move Electrons can be thought of as standing waves Only certain energy levels are possible Wave particle duality We model many things using mathematics For example, the equation of a line is y=a*x + b a stands for the slope b stands for the intercept We model an electron as a wave, described with an equation with four variables, the quantum numbers n l m l m s Primary Quantum Number...
