1. ATOMIC BASICS

2. ELEMENTS AN ELEMENT IS A SUBSTANCE MADE UP OF ONLY ONE KIND OF ATOM.

3. ATOMS THE SMALLEST UNIT OF MATTER MADE OF: PROTONS NEUTRONS ELECTRONS

4. ATOMS HAVE TWO REGIONS THE NUCLEUS AND ELECTRON CLOUD 1. NUCLEUS- MADE OF THE PROTONS AND NEUTRONS COMBINED. DETERMINES THE ATOM MASS.

5. 2. ELECTRON CLOUD - MAKES UP MOST THE ATOMS SPACE. ELECTRONS CIRCLE THE NUCLEUS IN RINGS.

6. NUCLEUS = NEUTRONS + PROTONS ELECTRONS

7. PROTONS HAVE A POSITIVE CHARGE ARE IN THE NUCLEUS = THE NUMBER OF ELECTRONS = THE ATOMIC NUMBER

8. NEUTRONS ARE FOUND IN THE NUCLEUS HAVE A NEUTRAL CHARGE

9. ELECTRONS HAVE A NEGATIVE CHARGE CIRCLE THE NUCLEUS IN RINGS = THE NUMBER OF PROTONS

10. ATOMIC NUMBER EQUALS # OF PROTONS(+) EQUALS # ELECTRONS(-)

11. ATOMIC MASS = PROTONS + NEUTRONS IN THE NUCLEUS

12. WHAT IS THIS ELEMENT? SINCE THERE ARE 6 ELECTRONS (-), THERE MUST BE 6 PROTONS (+). SINCE THERE ARE 6 PROTONS THE ATOMIC NUMBER IS 6. CARBON IS THE ELEMENT WITH AN ATOMIC NUMBER OF 6.

13. Dmitri Mendeleev INVENTED THE PERIODIC TABLE ELEMENTS ARE IN ROWS BY INCREASING ATOMIC NUMBER PERIODS - ROWS 1-7 GROUPS – COLUMNS 1-18

14. FAMILIES CAN BE 1 OR MORE COLUMNS THAT ARE GROUPED TOGETHER. THEY HAVE NAMES INSTEAD OF NUMBERS. ARE TOGETHER BASED ON REACTING THE SAME CHEMICALLY

17. ALKALINE EARTH METALS -REACTIVE METALS -THEY ALWAYS COMBINE WITH NONMETALS Image: http://www.learner.org/interactives/periodic/groups2.htmlhttp://www.learner.org/interactives/periodic/groups2.html

18. TRANSITION METALS GROUPS 3 – 12 LESS REACTIVE HARDER METALS CAN PUT 32 ELECTRONS IN THE LAST SHELL USED FOR JEWELRY Image: http://www.learner.org/interactives/periodic/groups2.htmlhttp://www.learner.org/interactives/periodic/groups2.html

19. BORON FAMILY MOST ARE METALS THEY HAVE 3 ELECTRONS IN THE OUTER SHELL Image: http://www.learner.org/interactives/periodic/groups2.htmlhttp://www.learner.org/interactives/periodic/groups2.html

20. CARBON FAMILY -IMPORTANT FOR LIFE - 4 ELECTRONS IN THE OUTER SHELL -CONTAINS METALS, METALLOIDS, AND A NON- METAL WHICH IS CARBON Image: http://www.learner.org/interactives/periodic/groups2.htmlhttp://www.learner.org/interactives/periodic/groups2.html

21. NITROGEN CONTAINS METALS, METALLOIDS, AND NON-METALS. MAKES UP 75% OF ATMOSPHERE 5 ELECTRONS IN OUTER SHELL Image: http://www.learner.org/interactives/periodic/groups2.htmlhttp://www.learner.org/interactives/periodic/groups2.html

22. OXYGEN CONTAINS METALS, METALLOIDS, AND NONMETALS REACTIVE 6 ELECTRONS IN THE OUTER SHELL Image: http://www.learner.org/interactives/periodic/groups2.htmlhttp://www.learner.org/interactives/periodic/groups2.html

23. HALOGEN GROUP ARE VERY REACTIVE ARE ALL NON- METALS USED AS DISINFECTANTS Image: http://www.learner.org/interactives/periodic/groups2.htmlhttp://www.learner.org/interactives/periodic/groups2.html

24. NOBLE GASES ARE GASES NON-METALS 8 ELECTRONS IN THE OUTER SHELL Image: http://www.learner.org/interactives/periodic/groups2.html http://www.learner.org/interactives/periodic/groups2.html

25. RARE EARTH METALS CONDUCT ELECTRICITY SOME ARE RADIOACTIVE Image: http://www.learner.org/interactives/periodic/groups2.htmlhttp://www.learner.org/interactives/periodic/groups2.html
