An atom refresher Matter is anything that takes up space and
has mass. All matter is made of atoms 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 in the electron cloud. An atom refresher Highlight

From the highlighted material create a chart in your ISN
listing the characteristics of the three subatomic particles.

Slide 9
What are elements? Elements are the alphabet to the language of
molecules. To make molecules, you must have elements. Elements are
made of atoms. While the atoms may have different masses and
organization, they are all built in the same way.
Slide 10
The nucleus of the atom houses the protons and neutrons.
Nucleus = Center Protons Positive Represented by a + sign + Neutron
no Charge Represented by a o or left blank o
Slide 11
Electrons a special place. Electrons exist in a cloud
surrounding the nucleus. Only so many electrons can be in any
certain shell, orbital, energy level. Now Electrons

More about Elements.. Elements are the building blocks of all
matter. The periodic table is a list of all of the elements that
can build matter. Its a little like the alphabet of chemistry. The
periodic table tells us several things
Slide 14
Periodic Table 8 O Oxygen 16 Atomic Number: Number of protons
and it is also the number of electrons in a neutral atom of an
element. Elements Symbol: An abbreviation for the element. Elements
Name Atomic Mass: Number of protons + neutrons. Periodic Table is
our next unit
