Modern Chemistry Review Ch. 5

Periodic Law
The physical/chemical properties of elements are periodic functions of their atomic numbers.
Ionization Energy
The energy it takes to remove one electron from a neutral atom
Electronegativity
the measure of the ability of an atom to attract electrons
Electron Affinity
Energy change that occurs when an electron is acquirred by a neutral atom
Menedeleev
Man credited with first periodic table of elements, categorized by elements with similar properties
