1. BELL WORK!
Pick up a handout and glue it in your composition notebook on page 64.
Quietly work on the handout.

2. Atomic # vs. Mass #

3. Determine the number of protons, neutrons, and electrons in the following…

4. Drawing Atoms Remember… The first electron cloud holds two electrons.
That electron cloud has to be full before you can draw another electron cloud.
The next electron clouds can hold 8 electrons.
Electron clouds have to be full before you can draw another electron cloud.
Draw the electrons on the electron cloud…not between the clouds.

5. Now…let’s draw them! Boron: First step…”PEN” it out for Boron! P=5 P=5
This is how you should draw the nucleus.

6. Challenge: Lithium
P = 3
N = 4

7. Challenge: Helium
P = 2
N = 2

8. Challenge: Neon
P = 10
N = 10

9. Challenge: Hydrogen
P = 1
N = 0

10. Today’s Assignment: Fold your paper into eight boxes.
Draw the following atoms in each of the boxes.
B1: Hydrogen
B2: Helium
B3: Lithium
B4: Beryllium
B5: Boron
B6: Carbon
B7: Nitrogen
B8: Oxygen
