AP CHEM LAB: CHEMICAL BONDING ? POLAR OR NONPOLAR THEORY: ?Two atoms held together by the mutual attraction of each nucleus to valence shell electrons are said to be chemically bonded. The chemical bond can be represented by the overlap of the electron probability density map of an atomic orbital from each atom to form a molecular orbital capable of containing two electrons. Or said in English, a covalent bond can form. These electrons are shared between the respective atoms. However, the degree of sharing is not necessarily equal. The electronegativity of each atom can be used to approximate its attraction for the electrons and therefore the probability of finding the electrons closer to that nuclei.

Chemical formula

Chapter 7 7-1 symbol? an abbreviation for the name of the element Chemical formula? a type of notation made with numbers and chem. Symbols To indicate the composition of a compound To indicate the number of atoms in one molecule of an element molecule? a single atom, a group of 2+ atoms of the same element, or a group of atoms of different elements that have combined to form a compound Monoatomic molecules? molecules with one atom Diatomic molecules? two atom molecules Hydrogen, oxygen, nitrogen, chlorine, fluorine, bromine, Iodine When writing the formula for a molecule of an element, write the number of atoms in each molecule as a subscript just after the symbol The formula of a compound tells 2 things: The element making up the compound

Matter Classified by? Physical State (Gas/ Liquid/ Solid) Composition (Element/ Compound/ Mixture) States of Matter Gas (vapor) No fixed volume or shape Uniformly fills its container Can be compressed to occupy a smaller volume Can be expanded to occupy a larger volume Molecules are far apart, move quickly, and often collide with the surrounding container Liquid Distinct volume (independent of container) No fixed shape (assumes shape of occupied container) Can't be compressed Molecules are packed closely but can still move (they flow over each other, reducing viscosity Solid Definite shape and definite volume Can't be compressed Molecules have fixed positions an wiggle only slightly *Temperature and pressure changes lead to phase changes of the substance
