Chemistry 141 Lecture Notes

Front 1

Atomic Theory

Back 1

1- all matter consists of atoms. 2- all atoms of an element are identical. 3- atoms combine in whole number ratios to form compounds. 4- chemical rxns are rearrangements of atoms. 5- atoms are indivisible.

Back 4

law of multiple proportions- come elements combine in more than one ratio but then ratios are whole number ratios of each other. but atoms are NOT indivisible.
