what does john dalton discovered?
ATOMIC THEORY OF MATTER
33
three laws that led with dalton's atomic theory
LAW OF CONSERVATION OF MASS
LAW OF DEFINITE PROPORTIONS
LAW OF MULTIPLE PROPORTIONS
34
can neither be created or destroyed
MASS
35
the total mass of the reactions and the products involved is conserved
LAW OF CONSERVATION OF MASS
36
if a compound is broken down into its constituent elements the proportions will remain the same
LAW OF DEFINITE PROPERTIES
37
if two elements form more than 1 compound between them the ratios of the masses of the second elemnt which combined with the fixed mass of the first elemtn will always be the ratio of small whole numbers
LAW OF MULTIPLE PROPERTIES
38
mass is always the same
LAW OF DEFINITE PROPERTIES
39
mass is not always the same
LAW OF MULTIPLE PROPOTIONS
40
no matter how you
make a chemical
compound, it have the
same ratio of elements

61
when the electrons of an atom absorbs energy like heat or electricity
EXCITED STATE

after the excited state, electrons eventually jump back to a lower energy level which releases an energy through light

85
requires that the electrons fill the orbitals in a sublevel, one by one , before pairing the electrons in an orbitals
HUND'S RULE
86
no two electrons can have the same four electronic quantum numbers, as an orbital can contain a maximum of only two electrons and the two electrons must have opposing spins
