Periodic Properties
elements in the same column of the periodic table have the same amount of this
valence electrons
the quantitative relationship between the rate and concentration
rate law
the nuclear charge that an electron in an atom experiences that is reduced by intervening electrons
effective nuclear charge
instantaneous rate
the energy required to remove one or more electrons from an atom
ionization energy
a substance that increases the rate of a reaction without going through a chemical change
catalyst
the energy change upon adding an electron to an atom in the gas phase, forming an anion
electron affinity
this is the name of the constant k in the rate law
rate constant
this gauges the size of the atom, based on measurements of distance in their chemical compounds
bonding atomic radius
in this order reaction, the rate is proportional to the concentration of a single reactant raised to the first power
first-order reaction
