4. Finish the Idea  The atomic number can be found on the_____ _____, that tell us the number of ______. Have you ever Have you ever wondered if there are other particles that make up the atom?

5. Examples or Nonexamples  Has a positive charge?  YES  Located outside the nucleus?  NO  Does the atomic number tells us how many there are?  Yes  Has a positive charge?  YES  Located outside the nucleus?  NO  Does the atomic number tells us how many there are?  Yes

6. Checking for Understanding  Think- Pair- Share  If the atomic number indicates the number of protons, how many protons does this element have??

7. Target Word Neutrons What is the word? Echo it with me. Neutrons What is the word? Echo it with me.

8. Student Friendly Explanation  have a neutral (0) charge and are located inside the nucleus. Sentence in Context Protons and neutrons make up the nucleus, which is held together by a strong force.

9. Finish the Idea  I can remember that a neutron has a _________ charge because neutron sounds similar. Neutrons are Neutral. Have you ever Have you ever wondered about the size of a neutron, proton and electron? Which do you think is smallest of the three?

10. Examples or Nonexamples Neutron: Thumbs Up, Thumbs Down  Has a neutral charge?  Yes  Can be found on the outside  Of the nucleus.  NO  Can be found located next to a proton  Inside the nucleus?  YES  Has a neutral charge?  Yes  Can be found on the outside  Of the nucleus.  NO  Can be found located next to a proton  Inside the nucleus?  YES

11. Checking for Understanding  Think- pair- share  In this figure what color is the neutron and state it’s location?

12. Target Word Electron What is the word? Echo it with me. Electron What is the word? Echo it with me.

13. Student Friendly Explanation  have a negative (-) charge and are location on the electron cloud. Sentence in Context The mass of an electron is almost 1,000 times smaller than the mass of a proton and the number of protons equals the number of electrons.

14. Finish the Idea  If the number of protons are the same as the electrons, where do you look to see the number of electrons? You look at the _______ _______. Have you ever Have you ever wondered how atoms combine with other atoms?

15. Examples or Nonexamples Electrons: Thumbs Up, Thumbs Down  Have a negative charge?  yes  Are bigger than protons  And neutrons?  NO  Are located on the electron  cloud?  yes  Have a negative charge?  yes  Are bigger than protons  And neutrons?  NO  Are located on the electron  cloud?  yes

16. Checking for Understanding  Think- pair- share  How many electrons are in this electron cloud?

17. Target Word Nucleus What is the word? Echo it with me. Nucleus What is the word? Echo it with me.

18. Student Friendly Explanation  the center of the atom that contains both the protons and the neutrons. Sentence in Context Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus, with a very small contribution from the orbiting electrons.

19. Finish the Idea  The protons and neutrons make up mostly all of the mass inside the _____. Have you ever Have you ever wondered what they used to see all of these small particle?

20. Examples or Nonexamples Thumbs Up, Thumbs Down  Holds the electrons?  No  Contains most of the  atom ’ s mass?  Yes  Electrons and Protons are  located here?  No  Holds the electrons?  No  Contains most of the  atom ’ s mass?  Yes  Electrons and Protons are  located here?  No

21. Checking for Understanding  Think- pair- share  What is inside the nucleus and what is their charge?
