Atomic models in order
Dalton, Thompson, Rutherford, Bohr, Electron Cloud Model
Democritus / Leucippus discovered
Atoms are the building blocks to life
Aristotle discovered
Matter (earth, fire, water, wind)
The side of the periodic table are the metals on
Left
Conductivity
The measure of the ease at which an electric charge or heat can pass through a material
How a cation forms and what it does to the atom
Loses electrons and makes element positive
How an anion forms and what it does to the atom
Gains electrons and makes element negative
Melleability
The ability of a material to be beaten into thin sheets without breaking
Luster
The appearance of a fresh surface of a mineral in reflected light
Mendeleev
Created periodic table
Valence electrons
The outer ring of electrons in the electron cloud
Where the charge / oxidation state can be found
The columns (+1, +2 skip a few, +3, +/- 4, -3, -2, -1, 0)
The way the period go
Horizontal rows
The way the families go
Vertical columns
Electronegativity
A chemical property that describes the tendency of an atom or a functional group to attract electrons toward itself
Atomic radius
The total distance from an atom's nucleus to the outermost orbital of electron
The way atomic radius goes
Top left to bottom right
The way covalent compounds are formed
A nonmetal with a nonmetal
The Lewis Structure
Showing how atoms gain/lose electrons
Metals
Shinny, ductile, malleable, and good conductors
Nonmetals
Brittle and poor conductors
Metals at room temperature
solid
Nonmetals at room temperature
gas
Metal’s melting point
High melting point
Nonmetal’s melting point
Low melting point
Metal’s solubility
Very soluble
Nonmetals solubility
Not very soluble
Balanced equation
2CO + 4T = 2CT^2 + 2O
Synthesis
A + B = AB
Decomposition
AB = A + B
Single Replacement
A + BC = AC + B
Double Replacement
AB + CD = AD + BC
Combustion
CxHy + 02 = H2O + CO2
Polar Bond
when electrons in a covalent bond are shared equally
Ways to Speed Up a Chemical Reaction
Increase surface area, increase temperature, increase concentration, and add catalyst
Ways to Slow Down a Chemical Reaction
Decrease surface area, decrease temperature, decrease concentration, and inhibitor
