This week, we will be exploring all kinds of geometric shapes – the vocabulary and the steps taken to construct them – as well as making our own patterns and

sketches from what we learn in class. We will take what we learn from this week and what we sketch and use it to help us design our stained glass artwork. For

chemistry, we will start exploring how atoms and elements are similar to us and how they have personalities of their own, which will be used in our mini-project

called “Which Element are You?”

Today you’re going to learn about the Periodic Table. The Periodic Table is a table that organizes different

type of atoms or elements in an easy-to read way. Elements are materials made out of just 1 type of

atom. Each box in the periodic table contains information about each type of atom. Take a look at the

periodic table at the back of this packet.

The first thing the periodic table tells is the name and the symbol of each element (type of atom). I want

you to practice with that:

Ex.

The element is hydrogen and the symbol is H.

Practice:

The element is __________ The element is __________

and the symbol is _____ and the symbol is _____

Now look at the periodic table on the back of the packet. Find the element names for all of these atomic

symbol.

1. Ca ________________ 7. F ______________ 13. Xe _______________

2. Zr ________________ 8. N ______________ 14. Po _______________

3. Na _______________ 9. Cl ______________ 15. Si _______________

4. Ge _______________ 10. Ar _____________ 16. Rn ______________

5. P ________________ 11. Kr _____________ 17. Al _______________

6. O ________________ 12. Br _____________ 18. Ni _______________

Find the symbols for these element names.

19. Copper _________________ 23. Molybdenum _______________

20. Tungsten _______________ 24. Strontium _________________

21. Barium _________________ 25. Magnesium ________________

22. Cesium _________________ 26. Silver ____________________

The second thing the periodic table tells you is the atomic number (the number of protons/electrons).

Ex.

Hydrogen’s atomic number is 1. It has 1 proton. And since it has 1 proton, to balanced out the atom, it has 1 electron

Practice:

Helium’s atomic number Lithium’s atomic number Atomic #:_______ Atomic #: ______ # of protons: ______ # of protons: ______ # of electrons: ______ # of electrons: _______

Element Atomic # # of protons # of electrons Element Atomic # # of protons

2. Zr 9. Cl

3. Na 10. Ar

4. Ge 11. Kr

5. P 12. Br

6. O 13. Xe

7. F 14. Po

The third you need to know is what we call the columns and rows of the periodic table. Going up and down on the periodic table (the columns) are called groups. Going left and right on the periodic table (row) are called periods. Go to the periodic table attached to the packet. Find HYDROGEN. Hydrogen is in group 1, period 1. Helium is in group 18, period 1. Cobalt (27) is in group 9, period 4. Calcium(20) is in group 2, period 4. Find the following elements: Cesium: period _______, group _______ Potassium: period _____, group _______ Lithium: period ______, group _______ Silicon: period _______, group ________ Sulfur: period _______, group _________ Argon: period _______, group __________

This number is the atomic number. It tells us that

hydrogen has 1 proton and 1 electron.

5. Three of the following statements are true. Draw a sketch or demonstrate each true statement. For each statement

that is false or wrong, draw a counterexample (an example to prove it wrong).

a. For every line segment there is exactly one midpoint.

b. For every angle there is exactly one angle bisector.

c. If two different lines intersect, then they intersect at one and only one point.

d. If two different circles intersect, then they intersect at one and only one point.

e. Through a given point on a line, there is one and only one line perpendicular to the given line.

f. In every triangle there is exactly one right angle.
