law of conservation of mass
matter is neither created nor destroyed
law of definite proportions
all samples of a given compound have the same proportions of their constituent elements
Law of multiple proportions
when two elements form 2 different compounds, the masses that combine can be expressed as a ratio of small whole numbers
charge of electron
-1.60x10^-19 C
what makes isotopes
different amount of neutrons, changing the mass
how to find atomic mass
sum of fractional abundance of isotope * mass of that isotope
metals
left side and bottom
shiny solids
conduct heat and electricity
malleable and ductile
variable charge on ions
non metals
right side and top
solids, liquids and gases
nonconductors
brittle solids
constant charge on ions
metalloids
between metals and nonmetals
shiny solids
brittle
semiconductors
constant charge on ions
what holds ionic compounds together
electrostatic charges
ionic compound
between cation and anion
transfer of electron to anion
naming acids
hydro to name of second element and replace end with ic acid
naming oxoacids
oxyanions with ate ending become acid named -ic acid
ite ending becomes acid names -ous acid
