Write the Question and the Answer
MYP Unit Question: How can such a small thing impact our
environment in such a big way?
Area of Interaction: Environment
Learner Profile: Inquirer & Knowledgeable – still learning and
gaining knowledge
Standard:
S8P1. Students will examine the scientific view of the nature of
matter.
a. Distinguish between atoms and molecules.
Learning Target: Today I will start to learn about atoms and its
sub-atomic components. This is important because all matter
on earth is made up with various combinations of atoms
Homework: Complete atom foldable

Structure of an Atom
Small positively
charged particle in the
nucleus of an atom.

Protons
Proton
Neutron
Particles with
no charge.
They are also
found in the
nucleus.
Neutron
So- what two particles are
found the nucleus?
Tiny, negatively charged, high
energy particle that moves in the
space outside the nucleus of an
atom called the electron cloud or
orbit.

Atomic Number
The number of protons in the nucleus of
an atom. This determines what the
element is.
 In a stable atom (no charge), there must be
an equal numbers of protons and
electrons.
 For example, the atomic number of
oxygen is 8, so there are 8 protons and 8
electrons in an oxygen atom.

Example: Oxygen Atom

If the atomic number of carbon
is 6, how many protons and
electrons does it have?
Carbon Atom
Atomic Mass

The average mass of one atom of an
element.

Mass # (rounded to nearest whole number)
= (# of Protons) + (# of Neutrons)

If a sulfur atom has an atomic mass of
about 32 and there are 16 protons,
how many neutrons will it have?

How are electrons really
arranged around the
nucleus?
0
2nd shell holds
8 electrons
1st shell holds
2 electrons
3rd shell holds
18 electrons
Electrons are arranged around the Nucleus in
SHELLS. This is also called the Electron Cloud.
Each shell can only hold a certain number of
electrons.
