Electrolyte
A substance that results in a solution that can conduct electricity
Electronegativity
Ability of an atom to attract electrons toward itself in a chemical bond
Nonelectrolyte
A substance that gives a solution that is not electrically conducting
Mixture
Combo of 2+ substances in which they retain their identity
Dilution
Procedure for preparing a less concentrated substance from a more concentrated substance
Nonpolar Molecule
Molecule that does not possess a dipole moment
Photon
Particle of light
Physical Property
Property that can be observed without transforming the substance into something else
Percent Yield
Ratio of actual yield to theoretical yield
Avogadro's Number
6.02 * 10^23
Endothermic Process
Absorbs heat from surroundings
Ionization Energy
Minimum energy required to move an electron from an isolated atom in its ground state
Compound
Substance composed of 2 or more elements chemically united in fixed proportions
Chemical Reaction
Process in which one or more substances are converted into other substances
Ionic Compound
Compound composed of cations & anions in which the total charges equal 0
Anion
An ion with a net negative charge
pH
Negative logarithm of the hydrogen ion concentration. Measures the amount of Hydrogen within a given substance.
Element
Substance that cannot be separated into simpler substances
Oxidation Number
Number of charges an atom would have if electrons were transferred completely in the direction of the atoms with the higher electronegativity
Kinetic Energy
Available energy from motion of an object
Nonmetals
Poor conductors of heat & electricity. Form negative ions
Isotopes
Same number protons, but different number neutrons
Molar Mass
The mass of 1 mole of atoms
Equilibrium
No observable changes as time goes by
Covalent Bond
2 electrons are shared by 2 atoms
Actual Yield
The amount of product actually obtained in a reaction
Inorganic Compounds
Compounds other than organic compounds
Heat
Transfer of thermal energy between two bodies at different temperatures
Energy
Capacity to do work or produce change
Molarity
moles/liters
Ion
A charged species
Density
mass/volume
Mole
Collection of Avogadro's number
Diffusion
Gradual of mixing of one substance with another
Metals
Good conductors of heat & electricity. Form positive ions.
Polar Bond
Covalent bond where the bonding electrons are more strongly attracted by one of the bonding atoms
Catalyst
A substance that increases the rate of a chemical reaction without itself being consumed
Joule
Unit of energy given in N/m
Nonpolar Bond
Covalent bond where electrons are equally shared
Molecular Compound
Compound consisting of atoms that are covalently bonded
Exothermic Process
Gives off heat to the surroundings
Ionic Bond
Electrostatic force that holds ions together
Hydrogen Bond
Dipole-dipole interaction between molecules containing hydrogen bonded to an electronegative element. Most important involve Nitrogen, Oxygen, & Fluorine
Octet Rule
An atom that forms bonds until it is surrounded by 8 valence electrons
Buffer Solution
A solution that has the ability to resist small changes in pH upon the addition of small amounts of either acid or base
Atom
The smallest piece of an element that can enter into chemical combinations
Enzyme
Biological catalyst
Molecule
2+ atoms held together by covalent bonds
Polar Molecule
Molecule that possesses a dipole moment
Cation
An ion with a net positive charge
