2. Why study Chemistry in Anatomy?
“Chemical reactions underlie all physiological processes.”

3. Introduction to Chemistry

4. Basic Chemistry Review
For Anatomy Students

6. Elements are substances made of only 1 kind of atom. ex: carbon, oxygen
The six most common elements found in living things are C, H, O, N, P, and S.

7. Atomic Structure

8. Atomic Structure atom - building blocks of matter
subatomic particles within the nucleus
protons + charge
neutrons no charge
around nucleus - cloud of – charged electrons

9. in most atoms, + and - are equal
# of protons = # of electrons

11. if an atom gains or loses an electron an ion is formed
loses electron → pos. ion
gains electron → neg. ion

13. sum of protons and neutrons
Atomic Mass
Atomic Number
sum of protons and neutrons
Number of protons
Number of electrons is equal to the number of protons
Atomic Symbol

15. Chemical Bonds
In an attempt to fill their levels to become stable, atoms will interact with each other:
covalent bonds share electrons

16. ionic bonds transfer electrons

17. Isotopes
variant of an element with same atomic number but different atomic mass
ex: radioisotope - heavier isotopes of many elements which are unstable and decompose
decay is radioactive

19. Uses for Isotopes

28. Molecular formulas show the specific ratios of atoms in a compound
Molecular formulas show the specific ratios of atoms in a compound. ex: H2O - made up of 2 hydrogen atoms and 1 oxygen atom
Water H2O
Carbon dioxide CO2
Oxygen O2
Glucose C6H12O6

33. Organic Compounds contain carbon covalently bonded
large - macromolecules
made by living things
