PM Quizlet
a combination of pure substances in variable proportions in which
individual substances retain chemical identities and can be separated
from one another in phyiscal processes
A property of a substance that can be observed without changing it into
another substance
ex) density
polyatomic anions containing oxygen in combination with one or more
other elements
Transformation of a sample of matter such as a change in physical
state but doesnt after chemical identity
Don't know?

The plum pudding model, proposed by J.J. Thomson in 1904,
described the atom as a sphere of positive charge with
negatively charged
electrons embedded within it, like plums in a pudding. This
model
followed Thomson's discovery of the electron but was later
replaced by Rutherford's nuclear model in 1911. The plum
pudding model marked a significant step in the development
of atomic theory.
