Chemical Interactions Notes: Substances
Chemistry is the study of _____________________ and changes in matter.
Matter is anything that has ________________________ and takes up _____________________________
(volume)
A __________________________________________ is a form of matter with a unique composition and
distinct _______________________________________, which are the traits, nature and behavior of
different kinds of matter.
Substances can be represented with a ______________________
chemical names, and chemical formulas.
__________________________,
Chemical names communicate information about the _____________________________ of
substances (What it is made of) example: sodium chloride
Chemical __________________ communicate the composition of substance, i.e. NaCl
Common names are familiar names or names we know substances by (i.e. NaCl is table salt)

An Element is:
-an unchangeable _______________________________________
-can not be _______________________________________________ down into simpler subsatnces.
-_______________________________________________________________ of all matter
___________________________________________________ has a mass and takes up space.
Elements and Matter
-
Elements _______________________________________________ to form all the different substances
(matter) in the world.
PROPERTIES
Chemical Properties: a chemical property is a property or behavior of a substance when
it undergoes a chemical change or ________________________________.
Physical Properties: the measurement of a physical property may
______________________________________ the arrangement of matter in a sample, but
NOT the _______________________________ of its molecules.
Example: water can be frozen, can be a liquid, or a gas but its chemical makeup does not
change.
Mendelev: Created the ____________________________________________ periodic table in 1869.
The _____________________________________________ that were most alike were grouped together in
the same _________________________________________________. He called those
____________________________________________________________________________________.
After arranging his version of the table, he noticed there were ______________________. This lead
him to predict that an _________________________________________________ element would fit.
Groups on the Periodic Table
Alkali Metals: Column ___________________________ very _______________________________ and
explosive in ______________________________________________.
Metals: 4 main characteristics of metals. It __________________________________________ electricity.
Halogens: very __________________________________________, often combining with metals and Alkali
Noble gas: will _________________________________________ react with ANY elements on the
periodic _____________________________________________.
