QuestionAnswer
Anion Negative Ion
Cation Positive Ion
Octet Rule Elements like to bond to give their valence shell 8 electrons.
Electronegativity Ability to hold and get electrons.
Flourine Element with greatest EN (4.0)
Covalent Bond Bond between nonmetals, electrons shared by the two atoms, melts more easily than an Ionic bond.
Ionic Bond Bond between a Metal and a Nonmetal, electrons taken by one atom and held together by ionic attraction
Metallic Bond Bond between a Metal and a Metal, electrons distributed equally
Francium Element with lowest EN (0.7)
Hydrogen, Nitrogen, Oxygen, Flourine, Chlorine, Bromine, Iodine The Diatomic elements.
Hydrogen, Lithium, Beryllium, Boron Exceptions to the octet rule.
Dmitri Mendeleev Arranged the modern Periodic Table
Johann Dobereiner Arranged the elements into "Triads"
Second Law of Thermodynamic All natural processes move towards a state of minimum energy.
Electron Affinity How much an atom wants electrons
Electron Sea Theory Atoms with weak ENs usually have only a few loosely held valence electrons. These atoms like to share their electrons.
117 Number of currently discovered elements
92 Number of naturally occuring elements
Henry Moseley Used X-Rays to count protons to find atomic numbers
Luster, Malleable, Conductive, Ductile Properties of metals
Lackluster, Brittle, Insulative, non-ductile Properties of nonmetals
Period Number Tells how many main energy levels the elements in that period have
Family Number Tells what kind of properties you can expect that element to have, and what it will bond with.
Element sizes increase as they go down the periodic table, and to the right
Element sizes decrease as they go up the periodic table, and to the left
