1. CHEMISTRY November 17, 2014 ATOMIC CONCEPT

2. SCIENCE STARTER You are seated and silent You have 5 minutes Do the SCIENCE STARTER

3. ANNOUNCEMENT MIDTERM – THIS FRIDAY MAKEUP QUIZ ARE ON QUIZSTAR HW01, HW03, HW04 AND HW05 ARE QUIZSTAR – http://quizstar.4teachers.org/

4. OBJECTIVES SWBAT: – APPLY THE KNOWLEDGE OF PROTONS, ELECTRONS AND NEUTRONS TO EXPLAIN WHAT HAPPEN TO THE ATOM WHEN AN ELECTRON IS REMOVED.

5. AGENDA THE ATOM FAMILY SCIENCE STARTER REVIEW FACTS ABOUT THE ATOMS WORK ON THE ATOMIC CONCEPT WORKSHEET COMPLET ANY OUTSTANDING WORK IN THE WORKSHEET

6. AIM What would happen to the morale of Matterville if one Elliott Electron was kidnapped?

7. CLAIM The morale of Matterville will be _______________ stable if one Elliot Electron was kidnapped.

8. EVIDENCE According to the article above, the morale of Matterville will be unstable if the number of Electron brothers is not balanced by the number of Proton sisters. There have to be one Electron brother for every one Proton sister.

9. JUSTIFY Protons and electrons relationship – Equal but opposite charges. – The number of protons equals the number of electrons in an atom.

10. ATOMIC FACTS Each atom has a nucleus, with an overall positive charge, surrounded by an electron cloud Nucleus includes protons and neutrons

11. ATOMIC FACTS Electron cloud includes negatively charged electrons.

12. ATOMIC FACTS Subatomic Particles: – Neutrons – no charge and have the heaviest mass – Protons - positive charge and have the 2 nd heaviest mass (almost as heavy as neutron) – Electrons – negative charge and have the least mass Protons and electrons relationship – Equal but opposite charges. – The number of protons equals the number of electrons in an atom. The mass of each proton and each neutron is approximately equal to one atomic mass unit (1 amu or 1 u). An electron is much less massive than a proton or a neutron. The proton is about 2000 heavier than an electron.
