Q

John Newlands (1837-1898)

A

Law of Octaves

120
Q

Lothar Meyer (1830-1895)

A

Made a prototype periodic table

121
Q

Dmitri Mendeleev (1834-1907)

A

Made a prototype periodic table; Created the Periodic Law; Predicted properties of undiscovered elements; “Father of Periodic Table”; Arranged elements by increasing mass and chemical property; Left spaces for elements not yet discovered; If arrangement by mass didn’t match arrangement by property, he arranged by property

122
Q

Henry Moseley (1887-1915)

A

Discovered atomic number

123
Q

Periodic Law

A

The chemical and physical properties of the elements are a periodic function of atomic mass*.
*Mendeleev said mass; modern definition is number

124
Q

Metals

A

Tend to form cations in aqueous solutions; tend to be lustrous, malleable, ductile, and good conductors of heat and electricity; tend to lose electrons in reactions; typically solids

125
Q

Nonmetals

A

Tend to form anions in aqueous solutions; tend to be dull, brittle, and bad conductors of heat and electricity; tend to gain electrons in reactions; often gases

126
Q

Metalloids

A

Staircase elements (B, Si, Ge, As, Sb, Te); Some characteristics of metals and some of nonmetals

127
Q

Alkali Metals

A

Family 1; Soft, metallic solids; found only in compounds in nature; low densities and melting points; low ionization energies; most reactive

128
Q

Alkaline Earth Metals

A

Family 2; Very reactive metals

129
Q

Transition Metals

A

Families 3-12

134
Q

Halogens

A

Family 17; Salt formers; Most reactive nonmetals

135
Q

Noble Gases

A

Family 18; Generally inert

136
Q

Inner Transition Metals

A

Lanthanides & Actinides

137
Q

Periodic Trends

A
  1. Atomic Radius
  2. Ionic Radius
  3. Ionization Energy
  4. Electronegativity
  5. Electron Affinity
138
Q

Driving Forces For Periodic Trends

A
  1. Stable octet (atoms are most stable with 8 electrons in outer electron layers)
  2. Electron shielding (equal within the same family, added electron layers reduce attraction between the nucleus and valence shell)
  3. Nuclear charge (equal within the same period, number of electron layers does not change, but number of protons in nucleus increases from left to right, increasing nuclear charge and nuclear attraction)
139
Q

Atomic Radius

A

Distance from nucleus to outer valence shell; increases top to bottom - more electron layers; decreases left to right - charge pulls electrons closer to nucleus as more protons are added

140
Q

Electronegativity

A

Tendency of one element to remove electrons from other elements; decreases top to bottom - nuclear charge decreases due to electron shielding; increases left to right - effective nuclear charge increases, but not atomic size

141
Q

Third Ionization Energy

A

Amount of energy needed to remove one mole of electrons from one mole of 2+ ions of the gas of the element; decreases top to bottom - electron shielding means easier to remove electrons; increases left to right - more energy to remove electrons from stable atoms (first 2 take more because removing electrons from stable octets)

142
Q

Electron Affinity

A

Energy released when an electron is added to atom; decreases top to bottom - electron shielding; increases left to right - increasing nuclear charge

143
Q

Principal Oxidation State

A

Typical charge of an ion of that element; increases to group 14, decreases to end; no top to bottom trend

144
Q

First Ionization Energy

A

Energy required to remove highest electron from neutral atom; decreases top to bottom - electron shielding; increases left to right - increasing nuclear charge

145
Q

Melting Point

A

Point at which element changes from solid to liquid; Metals - high melting point = metallic bonding; Metalloids - network solid = extremely high melting point; Nonmetals - lowest melting point = covalent bonding; lower melting points left to right - nonmetal bonds weaker

146
Q

Second Ionization Energy

A

Energy needed to remove second electron after 1 electron already removed; decreases top to bottom - electron shielding; increases left to right - increasing nuclear charge (first group larger)
