Living things may be study
in many different levels
These are (from smallest to
largest and more complex) :
Atoms & Molecules
Cells
Groups of cells
Organism
Population
Community
Ecosystem
Biosphere
electron
neutron
proton
THE ATOM



It is the basic unit of matter. Atomos “means
unable to cut”.
It has two areas: a nucleus and an electron cloud.
It contains subatomic particles that are even
smaller.
electron
neutron
proton
If all had the innocence of a child... a lot more
would get done, but a lot less would
be questioned... An open heart and a trained mind
brings both.
SUBATOMIC PARTICLES





The subatomic particles that make up the
atoms are protons, neutrons, and electrons.
Strong forces bind protons and neutrons
together to form the nucleus, which is at the
center of the atom. Here is the atom’s mass.
Protons and neutrons have the same mass, 1
atomic mass unit (amu). However, protons are
positively charged particles (+) and neutrons
have no charge (neutral).
The # of protons determines what type of
element is that particular atom.
The ATOMIC ENERGY comes from the nucleus.
SUBATOMIC PARTICLES (cont.)


Electrons (e-) are negatively charged
particles (-), that have a very small mass,
1/1840 of a proton.
The e- are in constant motion in the space
surrounding the nucleus called the
electron cloud.
Because atoms have equal #’s of e- and
protons, that have equal opposite
charges, atoms are neutral.
The e- is the part used by the atom to form
chemical bonds with other atoms, thus
forming matter.
QUESTIONS & SUMMARY
Using the High School Question Task
Cards, write two questions about the
levels of organization, and six
questions (regular) or eight
questions (honor) about the atom.
Write your summary for today’s
notes.
NOTEBOOK: OUTPUT
Write a 4 – 5 sentences paragraph about
the levels of organization that life shows.
You must use and underline at least four
(regular) or six (honor) key words.
Build a table that describes the parts of
an atom, and that includes the: name,
electrical charge, mass, place found, and
function, of each sub-atomic particle.
Name Charge Mass Location
Function

Watch the 14:00 minutes video, and
answer the questions:
What was the language used by
scientists to create the Periodic Table?
How are the atoms (elements) arranged
in the Periodic Table?
What makes one element different from
another one?
List and describe two uses given to the
periodic table in the professional
industry.
Name the elements with an atomic # of
31, and the one with the symbol Pb.
Elements & the Periodic Table
 A chemical element is a pure
substance. There are around
110 different elements.
 They are represented by 1 or
2 letters symbols, i.e., C =
carbon, and Na = ______
 The # of protons in an element
is the element’s atomic
number.
 They are organized in the
periodic table in periods (# of
shells or orbits), and groups
(# of electrons in the last shell)
Elements & the Periodic Table
THREE FORMULAS:
1 – ATOMIC NUMBER = # OF PROTONS
2 - ATOMIC MASS = # OF P + # OF N
(MASS NUMBER)
3 – ATOMIC CHARGE = # OF P - # OF eWHERE P = PROTONS, N = NEUTRONS,
e- = ELECTRONS

How do you find the mass number of an atom?
What is an isotope?
Do isotopes of the same element have different
chemical properties? Explain your answer.
Describe a radioactive isotope, and give three
examples of how are radioactive isotopes used.
What is a compound? And how is a compound
different from an element?
Name and describe two types of chemical bonds.
What is an ion? How do you create + and - ions?

WORD TENTS - EXAMPLE
The electron is a negatively charged
particle that moves around the nucleus.
In the nucleus we find the protons and
the neutrons, etc.
