Chemistry- I
Come in and make as
many
words as possible using A,
D, M
(you may use each letter
more than once)
Chapter 2
2.1: To learn about the composition of matter
2.2 To learn the differences between
elements and compounds
2.3 The States of Matter
2.1 The Particulate Nature of
Matter

Matter


has mass
Occupies space
Some definitions

Atom (matter is made up of tiny particles)
The shape of an atom is roughly
spherical. There are about 100 different
types of atoms.
How many words did you make up with the
3 letters?



Compounds: substances made by bonding
atoms in specific ways. These substances
contain two or more different types of atoms.
Compounds always have the same
composition. (Hydrogen Peroxide)
Law of Constant Composition: although it
contains more than one type of atom, a
compound always has the same combination of
atoms (composition)
Molecule can be one or more types of atom
that share electrons. (Oxygen, Water)
Examples of Compounds
Elements are substances that contain
only only one type of atom
 Allotrope: Element that exists in several
forms (Example: carbon)

All that Matters

There are many ways to classify the materials we see around us
every day. Is it a solid, liquid, gas, or plasma? Is it an element or a
compound? Is it a pure substance or a mixture? The answers to
these questions allow us to identify the things we see. For example,
we learn to tell the difference between an apple and a banana, or
either of those from a ham sandwich. All of these items are food,
they all have nutrients, like vitamins and minerals, but they are not
identical. Without the ability to observe the environment and
identify what we are seeing, we would be unable to respond to and
use the materials around us.
NAME SOME PROPERTIES THAT YOU WOULD USE TO TELL THE
DIFFERENCE BETWEEN A BANANA AND A HAM SANDWICH. TRY
TO THINK OF PROPERTIES THAT COULD BE USED TO TELL ANY
BANANA FROM ANY HAM SANDWICH.
2.3: The Three States of Matter



Solid: has a fixed shape and volume
Liquid: has a definite volume but takes the
shape of the container.
Gas: has no fixed volume or shape.
