2. #1
Negatively charged particles that surround the nucleus of the atom.

3. #2
Equals the number of protons + neutrons in the atomic nucleus

4. C6 N7 O8 F9 #3 Equals the number of protons (p+) in the nucleus
Each element has its own number of p+
C6 N7 O8 F9

5. #4
These are located around the nucleus and are home to electrons.

6. #5
An atom’s outer electrons

7. #6
This model of the atom only shows the outer electrons

8. #7 Is the average mass of all of the isotopes for a particular element
Is shown as a decimal

9. #8
This model shows an atom’s protons, neutrons and electrons.

10. #9
This number is positive if an atom loses electrons and negative if an atom gains electrons.

11. #10
These are located horizontally in the PT

12. #11
These are vertical columns in the PT

13. #12
Different forms of the same element with the same # of p+ but different #s of no
Ex.
