Chemistry Study of the elements of the periodic table
Chemistry Science that investigates the molecular reasons for the processing occurring in
the macroscopic world.
, Chemistry Study of matter and how matter reacts
Chemistry The field of study concerned with the characteristics, composition, and
transformations of matter
Matter anything that occupies space or has mass
Element building blocks of nature, CANNOT be broken down into other substances
Compound chemical combination of elements, CAN be broken down into elements
ex: acetaminophen (ingredient for mixture)
Pure substance elements and compounds, which always have the same composition throughout
their structure
Mixture physical mixing of compounds and /or elements, CAN be separated into pure
substances ex: Tylenol
HOMOgeneous substance that is SAME throughout, uniform
HETEROgeneous substance that is not the same throughout, consists of visibly distinguishable parts
Liquid has a definite volume and indefinite shape, does flow
-> only Mercury (Hg) and Bromine (Br)
Solid has definite volume and shape, does not flow
-> most elements (radioactive)
Gas has an indefinite volume and shade, does flow
->H, N, O, F Cl, and all noble gases
