1. Chemistry of Life Atoms, atoms, everywhere

2. Matter Matter is anything with mass and volume

3. Matter Matter is anything with mass and volume Mass is the amount of matter

4. Matter Matter is anything with mass and volume Mass is the amount of matter Volume is the amount of space the matter takes up

5. Matter Matter is made of atoms

6. Atoms Atoms are made of subatomic particles

7. Atoms Atoms are made of subatomic particles Protons in the nucleus

8. Atoms Atoms are made of subatomic particles Protons in the nucleus Neutrons in the nucleus

9. Atoms Atoms are made of subatomic particles Protons in the nucleus Neutrons in the nucleus Electrons orbiting outside the nucleus

10. Atoms Atoms are made of subatomic particles Protons in the nucleus Neutrons in the nucleus Electrons orbiting outside the nucleus Mostly its empty space!

11. Elements Each element has atoms that are alike, but different from other elements

12. Elements Each element has atoms that are alike, but different from other elements Elements can't be broken down into simpler matter

13. Elements Each element has atoms that are alike, but different from other elements Elements can't be broken down into simpler matter Elements are arranged on the periodic table

14. Elements Six elements make up all living things

15. Elements Six elements make up all living things S, P, O, N, C, H

16. Compounds Most elements don't exist by themselves

17. Compounds Most elements don't exist by themselves Compounds are atoms that are joined together with bonds

18. Compounds Most elements don't exist by themselves Compounds are atoms that are joined together with bonds There are two main ways of bonding:

19. Compounds Most elements don't exist by themselves Compounds are atoms that are joined together with bonds There are two main ways of bonding: Covalent bonds

20. Compounds Most elements don't exist by themselves Compounds are atoms that are joined together with bonds There are two main ways of bonding: Covalent bonds Ionic bonds

21. Covalent Bonds Happen when atoms share electrons

22. Covalent Bonds Happen when atoms share electrons Molecules have exact proportions of elements

23. Covalent Bonds Happen when atoms share electrons Molecules have exact proportions of elements Example: water

24. Covalent Bonds Happen when atoms share electrons Molecules have exact proportions of elements Example: water Formula: H 2 O

25. Ionic Bonds Happen when atoms transfer electrons

26. Ionic Bonds Happen when atoms transfer electrons Ions stick together because of electric charge

27. Ionic Bonds Happen when atoms transfer electrons Ions stick together because of electric charge Example: table salt

28. Ionic Bonds Happen when atoms transfer electrons Ions stick together because of electric charge Example: table salt Formula: Na+Cl-
