4. VOCABULARY
SUBATOMIC PARTICLES
PROTON
NEUTRON
ELECTRON

5. smaller parts of an atom
SUBATOMIC PARTICLES
smaller parts of an atom

6. subatomic particle with a positive charge (+1)
PROTON
subatomic particle with a positive charge (+1)

7. subatomic particle that is neutral (no charge)
NEUTRON
subatomic particle that is neutral (no charge)

8. subatomic particle with a negative charge (-1)
ELECTRON
subatomic particle with a negative charge (-1)

9. Where are the subatomic particles located?
LOCATION
Where are the subatomic particles located?

10. The proton and neutron are located in the nucleus.
LOCATION (ANSWER)
The proton and neutron are located in the nucleus.
The electron is located outside of the nucleus in the electron cloud

11. OVERALL CHARGE OF THE NUCLEUS
What is the overall charge of the nucleus?

12. LABEL THE ATOM

13. OVERALL CHARGE OF THE NUCLEUS (ANSWER)
The overall charge of the nucleus is positive.

14. OVERALL CHARGE OF AN ATOM
What is the overall charge of the atom?

15. OVERALL CHARGE OF AN ATOM (ANSWER)
Overall, the atom is neutral

16. Which subatomic particles have equal but opposite charges?

17. OPPOSITE CHARGES (ANSWER)
The proton and the electron have equal but opposite charges.

18. QUANTITY RELATIONSHIP
What is the quantity relationship between protons and electrons for an atom?

19. QUANTITY RELATIONSHIP (ANSWER)
There is a 1:1 relationship. In other words, there are an equal number of protons and electrons.
Example: Hydrogen atom has one proton, than hydrogen atom has one electron.
