An Introduction to the Periodic Table Column/Families/Groups Tell us how many valence electrons are in the outermost s and p shells Elements with similar properties are found in the same group Rows/Periods Tell us which shell the valence electrons are found; each row...
Electromagnetic Radiation (EMR) EMR: energy that exhibits wavelike behavior and travels thru space at the speed of light in a vacuum Ex: light from the sun, X-rays All EMR travel at speed of light Each form of EMR is only different in wavelength Photon: tiny particle...
Notes Reaction Stoichiometry: mass relationships between reactants and products in a chemical reaction Mole Ratio: conversion factor that relates amount in moles of two substances in chemical reaction Coefficients convey ratio of substances needed for the reaction to...
Mass Spectroscopy Why are atomic masses not whole numbers? Because they are weighted averages of isotopes Mass spectroscopy: study of the manner in which substances interact with electromagnetic radiation Isotopes: atoms with the same number of protons (same element)...
