Atomic structure
particle with positive charge
proton
elements in the same group share this
same valence electrons
this bond shares electrons
covalent
matter cannot be created or detroyed
law of conservation of mass
A+B=AB
synthesis
atomic number equals
number of protons
atomic radius increases this direction
down and to the left
this bond forms between metals and nonmetals
ionic
avegrado numbers
6.022x10^23
AB->A+B
decompostition
no two same charge particles can occupy same quantum state
electronegativity increases this way
Up and to the right
polraity is caused by this
unequal electrons
coefficiants in balanced equations
mole ratio
AB+C -> AC+B
Single replacement
what determines element chemical properties
valence electrons
Group 1 elements are called
alkali metals
determines whether a covalent bond is polar or nonpolar
electronegativity
the smaller reactant
limiting factor
AB+CD -> AD+CB
Double replacement
ions differ in
electrons
Noble gases are unreactive because of
Full valence shell
this intermolecular bond is the strongest
hydrogen bonding
maximum amount of product that can be prouced from balanced equation
theoretical yield
reaction that involves oxygen
combustion
