Remember!
 We
have learned there are 2 ways to represent a
neutral atom of an element:
Sodium
+
Lets try our math a different way today!
Atomic # = __________
Atomic Mass = ________
# of Protons = _________
Element Name: ________
# of Neutrons = ________
Element Symbol: ______
# of Electrons = ________
+
One More Time…
Atomic # = __________
Atomic Mass = ________
# of Protons = _________
# of Neutrons = ________

REVIEW: What happens when you
mess with subatomic particles?
 What
happens when you change the
number of protons?
 What
happens when you change the
number of electrons?
 What
happens when you change the
number of neutrons?

REVIEW: IDENTITY

If you add two protons to the element
Zinc, which element will it become?

If you take three protons away from
Copper, which element will it
become?
+
REVIEW: IONS

If Beryllium loses 2 electrons, will it
have a negative or positive charge?
Will it be an anion or cation?

If Chlorine gains 1 electron, will
charge will it have a negative or
positive charge? Will it be an anion or
cation?
+
REVIEW: ISOTOPES

If you have Carbon-12 and add one
neutron to it then it becomes…

If you have Sodium-22 and take three
neutrons away from it then it
becomes…
+
IN SUMMARY…

PROTONS = IDENTITY

ELECTRONS = ION (CHARGE)

NEUTRON = ISOTOPE (MASS)

CLASSWORK/HOMEWORK
Create
your own…
“Atoms Family Album”
•
Fold the album together in a way that you would like, but it
must have room for all 5 family members
YOU MUST INCLUDE:
•
•
•
a representative drawing/printed picture and a description of
the following family members:
PROTON, NEUTRON, ELECTRON, ION, (both anion & cation
must be represented) & ISOTOPE
+
Quiz Time!
Close
your notebook
Open
the textbook to page D-20 to use
the Periodic Table…this is the ONLY
thing your are allowed to use!
When
you are finished, please put
your quiz in the basket and begin
working on your Atoms Family Album!
