2. Agenda
1) Warm-up and C-note set-up
2) Activity and Notes
3) Concept Map
4) Review Time
5) Jeopardy
No homework today. Study for your test on Friday
3. Set up C-Notes
Please set up your C-Notes for today.
Topic: Atomic Number and Isotopes
Focus Question: What determines which element
an atom will be?
Then answer this warm-up question
Write one thing that you learned in this unit,
and one thing you have a question about.
Mr. Lee will choose 3 students to share.
4. Team Building Activity
Line up by oldest to youngest in the class.
For example, if your birthday is 12/25/1999, you
would stand in front of your friend whose birthday
is 1/24/2000.
Rule: Again, complete this activity with no talking.
Use non-verbal communication skills. See how
quickly you can form this line.
5. Atomic Number
Please copy all notes in green
Much like you all did with your birthday, the
periodic table is ordered from beginning to end by
a special number. The periodic table is ordered
from lowest atomic number (1) to highest atomic
number.
What is the atomic number?
6. Atomic number is the number of protons in an
atom. Every element has a different number of
protons.
The atomic number is written at the top of every
element in the periodic table.
7.
8. Changing the number of electrons or neutrons in
an atom will not change the element.
Ex: Na (Sodium) naturally has 11 protons, 11
neutrons, and 11 electrons.
- If you change the number of electrons to 12, or
neutrons to 12, it will still be sodium
- If you change the number of protons to 12, it
will become magnesium
9. Why? Because the number of protons determines
what element an atom will be.
10. Quick Notes on Isotopes
Isotopes are atoms that have a different number
of neutrons. Mass number is the sum of protons +
neutrons in an atom.
For example: Carbon naturally has 6 protons, 6
electrons, and 6 neutrons.
The isotope Carbon-13 has 6 protons, 6
electrons, and 7 neutrons. Mass # = ?
The isotope Carbon-14 has 6 protons, 6
electrons, and 8 neutrons. Mass # = ?
11. Review questions
Answer these questions in the “Summary” section
of your Cornell Notes
1) What # determines how elements are ordered
on the periodic table?
2) What is the atomic #?
3) What is mass #?
4) What are isotopes?
5) What sub-particle determines what element an
atom will be?
12. Jeopardy
Rules: Mr. Lee will select a student with his
popsicle sticks. That student has three seconds to
decide to answer or pass.
If the student chooses pass, Mr. Lee will select
another popsicle stick.
If the student chooses to answer, he/she will have
10 seconds to discuss with their group and then
give the answer.
If that student is correct, they will earn the amount
of points for that question. If they are wrong, they
will lose that amount.
13. The winning team will earn 5 points extra credit on
their test on Friday. Mr. Lee will choose a
scorekeeper who will earn 2.5 points but will not
play in the game.
Since this is Jeopardy, you MUST answer in the
form of a question. Let's demonstrate.
14. This famous basketball player had many
nicknames, one of them being “His Airness”
(To get this right, you must respond in the form of
a question)
16. There is a Bonus Question, a Double Jeopardy,
where you can wager any amount of $ before
answering the question, and a final Jeopardy
where instructions will be given.
Let's demonstrate double jeopardy
17. Double Jeopardy! How much will you wager?
Give a $ amount. You will win this much if correct
and lose this much if incorrect.
18. This famous 2-time finals MVP was named after a
delicious steak his father ate in Japan.
