Transcript Periodic Table

Periodic Table
Objective: We will be able to
explain what the periodic table is
and how it is organized.
Prior Knowledge
• We already know that all matter is made
from atoms and that atoms make up the
elements.
• Name the particles that make up an atom
TPS: What is the
center of an atom
called? 1?
What particles
make up the
center of an
atom? 2 ?
3electrons
1
TPS: What
particles are
always on the
outer shells? 3?
2
Protons
And
Neutrons
Today we will learn how atoms are arranged on the periodic table.
Concept: Periodic Table
Periodic Table:
1. Contains all known elements
2. Each element has a name, chemical symbol,
and atomic number
3. Organized by the elements' chemical property,
which is their Atomic Number
TPS: In your own words explain how the periodic
table is organized.

Periodic Table
•Each column is called a group
•Elements in a group have alike
properties
Choral:
What is this
group called?
Noble
Gasses

Periodic Table:
1.
Contains all known elements
2.
Each element has a name, chemical symbol, and atomic number
3.
Organized by the elements' chemical property, which is their Atomic Number
Each element is arranged in a
box on the Periodic Table.
The box contains the element’s
chemical properties
The atomic number stands for
the number of protons in the
nucleus.

C
Carbon
A chemical symbol is a short
form of the element’s name.
TPS: What information can be found about an element in the box on the periodic
table?

•Colors-shades, indicate whether the elements are metals,
semimetals, or nonmetals
Metals
Semimetals
Nonmetals
TPS: What do the colors-shades, indicate about the elements?
What would the classification be of the Noble Gasses and other darkly
shaded elements?

Relevance
It is relevant to learn about the periodic table
because:
1. In the past people believed that there were
only 4 elements now we know that there are
over 100 elements
2. Everything is made of elements
3. A reason of your own.
TPS: Which reason is most relevant to you?
Concept Closure
Skill closure:
• TPS: What type of element does each color- shade,
on the periodic table represent?
Key
– How do you know?
Metals
Semimetals
Nonmetals
• WB: Draw a periodic table box containing an element
from the noble gas group. Label the parts.
Concept Closure:
• Exit Ticket : In your own words explain how the
periodic table is organized.
