1. THE CHEMICAL BASIS OF LIFE

2. EMERGENT PROPERTIES – HYDROGEN AND OXYGEN INDIVIDUALLY VERSUS H 2 O

3. THE CHEMICAL BASIS OF LIFE LIFE IS MADE UP OF 25 ELEMENTS – WHAT IS AN ELEMENT? – 92 NATURALLY OCCURING ELEMENTS 25 ARE NECESSARY FOR LIFE WHAT ARE THE MAJOR ELEMENTS? WHAT ARE THE TRACE ELEMENTS?

4. THE CHEMICAL BASIS OF LIFE TRACE DOESN’T MEAN USELESS!!! SAY HI TO A “GOITER”

5. THE CHEMICAL BASIS OF LIFE ELEMENTS CAN COMBINE TO FORM COMPOUNDS HOW AND WHY DOES THIS OCCUR??

6. THE CHEMICAL BASIS OF LIFE ELEMENTS CAN COMBINE TO FORM COMPOUNDS – WHAT IS AN ATOM? SUBATOMIC PARTICLES – PROTONS – NEUTRONS – ELECTRONS – WHAT DOES AN ATOM LOOK LIKE?

7. THE CHEMICAL BASIS OF LIFE

8. WHAT GIVES DIFFERENT ELEMENTS THEIR DIFFERENT PROPERTIES? – ATOMIC NUMBER – ATOMIC MASS WHAT ARE ISOTOPES?

9. THE CHEMICAL BASIS OF LIFE RADIOACTIVE ISOTOPES CAN BE USEFUL IN RESEARCH AND MEDICAL DIAGNOSIS

10. THE CHEMICAL BASIS OF LIFE ELECTRON ARRANGEMENTS DETERMINE THE CHEMICAL PROPERTIES OF AN ATOM – ELECTRON SHELLS

11. THE CHEMICAL BASIS OF LIFE ELECTRON ARRANGEMENTS DETERMINE THE CHEMICAL PROPERTIES OF AN ATOM – VALENCE SHELLS

12. THE CHEMICAL BASIS OF LIFE ELECTRON ARRANGEMENTS DETERMINES THE CHEMICAL PROPERTIES OF ATOMS – WHAT IS A CHEMICAL BOND? – WHY DO THEY OCCUR?

13. THE CHEMICAL BASIS OF LIFE CHEMICAL BONDS – TYPES OF CHEMICAL BONDS? – VIDEOS VIDEOS

14. THE CHEMICAL BASIS OF LIFE IONIC BONDS VS IONS VS IONIC COMPOUNDS

15. THE CHEMICAL BASIS OF LIFE COVALENT BONDS

16. THE CHEMICAL BASIS OF LIFE COVALENT BOND

17. THE CHEMICAL BASIS OF LIFE COVALENT BONDS FORM MOLECULES – WHAT IS A MOLECULE? COVALENT BONDS ALLOW MULTIPLE ELECTRONS TO BE SHARED AT THE SAME TIME RESULTING IN?? – DOUBLE BONDS – TRIPLE BONDS

18. THE CHEMICAL BASIS OF LIFE DOUBLE BONDS

19. THE CHEMICAL BASIS OF LIFE TRIPLE BONDS

20. THE CHEMICAL BASIS OF LIFE MOST IMPORTANT TYPE OF BOND??

21. THE CHEMICAL BASIS OF LIFE COVALENT BONDING DOESN’T NECESSARILY MEAN EQUAL SHARING!!! – POLAR VS NON-POLAR MOLECULES – ELECTRONEGATIVITY

22. THE CHEMICAL BASIS OF LIFE WATER IS THE MOST IMPORTANT POLAR MOLECULE – VIDEO VIDEO

23. THE CHEMICAL BASIS OF LIFE WATER’S POLARITY LEADS TO HYDROGEN BONDING

24. THE CHEMICAL BASIS OF LIFE WATER’S POLARITY AND HYDROGEN BONDING GIVE WATER SOME UNIQUE PROPERTIES – COHESION – ADHESION – SURFACE TENSION – HEAT CAPACITY – DENSITY DILEMMA? – UNIVERSAL SOLVENT

25. THE CHEMICAL BASIS OF LIFE ACIDS AND BASES – PH SCALE – BUFFERS

26. THE CHEMICAL BASIS OF LIFE ACIDS VS BASES

27. THE CHEMICAL BASIS OF LIFE CHEMICAL REACTIONS REARRANGE MATTER – H 2 + O 2  H 2 O (REACTANT VS PRODUCT??) – C 40 H 56 + O 2 + 4H  2C 20 H 30 O (SUBSCRIPT VS COEFFICIENT??)

28. THE CHEMICAL BASIS OF LIFE MORE TO COME!!! TUNE IN NEXT WEEK, SAME BAT TIME, SAME BAT CHANNEL!!
