1.What is the difference
between atoms,
elements, molecules,
and compounds?
Created by G.Baker www.thesciencequeen.net
Matter is anything
that takes up
space and has
mass.
All matter is made
of atoms

What are atoms?
The smallest amount
of an element.
Atoms are the
building blocks of
matter, (sort of how bricks are
the building blocks of houses.)

 An atom has three
parts:
 Proton = positive
 Neutron = no charge
 Electron = negative
 The proton & neutron
are found in the center
of the atom, a place
called the nucleus.
 The electrons orbit the
nucleus.

What are elements?
A basic substance
that can't be
simplified
(hydrogen, oxygen,
gold, etc...)
What are Molecules?
2 or more atoms
that are chemically
joined together (H2,
O2, H2O, etc...)

What are compounds?
• A molecule
that contains
more than one
element (H2O,
C6H12O6, etc...)

Summary:
 Atoms combine to make
Molecules
 Molecules can be either
elements(2+same type of
atom) or compounds (2+
different atoms combined)
 These all combine to make
MATTER.

Understanding Elements on the
Periodic Table (DRAW ME)
Atomic Number:
Number of protons and it is also the
number of electrons in an atom of an
element.
Element’s Symbol:
An abbreviation for the
element.
8
O
Elements Name
Oxygen
Atomic Mass/Weight:
16
Number of protons +
neutrons.
Atomic Math: To figure out the number of Neutrons you:
Subtract the ATOMIC NUMBER from the Atomic Mass (16-8=8)
