What is Matter?
Anything that can be smelled, tasted,
touched…
Has
and
(takes up space)
Matter exists in some
or phase
Most common are solid, liquid, gas. But
non-newtonian, & plasma are often used
Matter is made up of
word ATOM comes from
Democritus. It means “
. The
”
Atomic Theory: It is thought that atoms are
made of
. Most
common particles are:
- has a positive Charge
- has a neutral charge; has
both positive and negative attributes
- has a negative charge
Atom
Smallest part or piece of matter that still
has the properties of matter
: Positively charged particle;
largest of three particles; symbol is
: Neutrally charged particle; has
both positive and negative charges; slightly
smaller than proton; symbol is
: Negatively charge particle; 2000
times smaller than proton; symbol is
Atomic Structure:

Periodic Table
First organized using the known properties
from other chemists like Stanislao
Cannizzaro, Dmitri Mendeleev created the
table of elements in 1869
of elements
Organized horizontally
Indicates # of electron levels
of elements
Organized vertically
Indicates # of electrons in outer cloud
(# of P+)
(Often from Latin or Greek)
(1st letter is upper case, 2nd is lower case)
(# of P+ & N=)
# of ___________ in each cloud

Q:
How can we calculate the
# of Neutrons?
Bonding:
Atoms join together to form molecules of a
compound through bonding. The
most common way to bond is by
sharing
.
The first three periods of elements are the
easiest to understand. The most eheld in the outer cloud of these
elements is
. In order to become
more stable, elements will share e-.
