be personal or academic! Explain why you enjoy those two
things.

4. Why shouldn’t we feed peanuts to monkeys?
5. If you ARE going to feed ducks, what should you feed
them instead?
Learning Target:
● I can classify and explain the structure of an atom.
I can classify and explain the structure of an atom, element, compound, mixture, as well as, the organization of the
periodic table and the modern atomic theory.

In addition to mastering level
3, I make in-depth
inferences and applications
that go beyond what was
taught in class.
3
I am able to classify:
• atoms, elements, compounds,
mixtures
• heterogeneous/homogeneous
mixtures
I am able to explain:
• the organization of the periodic
table (families, groups, periods,
reactivity, and atomic number)
• the modern atomic theory
2
I can define the following terms:
•
Atom
•
Element
•
Compound
•
Mixture
•
Heterogeneous mixture
•

•
Periodic Table
•

Answer the following question: An atom is the smallest
particle into which an element can be divided and still
be that element. Now that scientists have learned that
an atom is made up of even smaller particles, is this
definition still accurate?
Explain your answer in your science journal.

How Small Is an Atom?
• Three One-Hundred-Millionths of a Centimeter!
Scientists know that aluminum is made of
average-sized atoms. An aluminum atom has a
diameter of about 0.00000003 cm.

What Is an Atom Made Of?
• The Nucleus Protons are positively charged
particles in the nucleus. Neutrons are the particles of
the nucleus that have no electrical charge.
• Outside the Nucleus Electrons are the negatively
charged particles in atoms. Electrons are found around
the nucleus within electron clouds. All the structures of
the atom can be seen on the next slide.

How Do Atoms of Different Elements Differ?
• Starting Simply The
hydrogen atom has one
proton and one electron.
• Now for Some
Neutrons The helium
atom has two protons, two
neutrons, and two
electrons.

Section 2 The Atom
How Do Atoms of Different Elements Differ?
• Building Bigger Atoms For bigger atoms, simply
add protons, neutrons, and electrons.
• Protons and Atomic Number The number of
protons in the nucleus of an atom is the atomic number
of that atom. All atoms of an element have the same
atomic number.
