  1. DO NOW • Read The Chemistry of Life Introduction • Read, underline, highlight, and ASK QUESTIONS. • Is there anything you have heard of?

  2. The Chemistry Of Life Unit 2

  3. Why are we studying chemistry? “What are you made of? Just as buildings are made from bricks, steel, glass, and wood, living things are made from chemical compounds. When you eat food or inhale oxygen, your body uses these materials in chemical reactions that keep you alive. If the first task of an architect is to understand building materials, then the first task of a biologist is to understand the chemistry of life.”

  4. The Basic Unit of Matter • Atom- smallest unit, or part, of any “thing.” • Atom comes from Greek word atomos- “unable to be cut” • 100 million atoms

  5. PAUSE. • What is the smallest unit of matter called?

  6. Subatomic Particles • Sub-marine • Sub-zero • Sub-atom-ic There are 3 particles found within an atom: • Protons • Neutrons • Electrons Particles- “Small things”

  7. PAUSE. • What does “subatomic” mean?

  8. PAUSE. • What does “subatomic” mean? • What are the 3 “subatomic” particles?

  9. Subatomic Particles Carry a Charge • Protons- positive charge (+) • Neutrons- neutral, or no charge • Electrons- negative charge (-)

  10. Protons (+) and Neutrons have the same weight. • Protons (+) are Neutrons make up the Nucleus, which is at the center of an atom. • Electrons (-) are found outside the nucleus.

  11. PAUSE. • What is the charge on a proton? • What the charge on an electron? • What is the charge on a neutron?

  12. PAUSE. • Where do we find protons and neutrons in an atom? • Where do we find electrons in an atom?

  13. Protons (+) and Neutrons in the Nucleus

  14. Protons (+) and Neutrons in the Nucleus Electrons (-) stay outside the nucleus

  15. Protons (+) and Neutrons in the Nucleus (Living that life) Electrons (-) stay outside the nucleus (Haters)

  16. PAUSE. • Where do we find PROtons and NEUtrons?? • Where do we find electrons (-) ??

  17. Atoms have the same number of protons (+) and electrons (-) • Same amount of positive (+) and negative (-) charges • Overall charge of an atom is NEUTRAL

  18. What is an “atom?” • What are the 3subatomic particles of atoms?

  19. DO WE UNDERSTAND?!?!Questions!?!

  20. What is the charge of a proton? • What is the charge of a neutron? • What is the charge of an electron?

  21. What is the center of an atom called? • Where do we find protons, neutrons, and electrons in an atom?

  22. What is the “overall charge” of an atom and WHY?

  23. Elements • A pure substance composed of just 1 type of atom • Pure- not mixed with anything else • Composed- made of

  24. C 6 Carbon 12.01

  25. C 6 # of protons Symbol for Element Name of Element Carbon 12.01 Atomic weight
