Bell Ringer: 02/27/17 Objective: Use appropriate terminology in the context of studying chemistry, including atom, element, molecule, and compound. Question: Write the photosynthesis equation.

Where can I find chemicals in my body? A chemical is a substance that is made up of elements/molecules and used in chemical reactions.

KEY TERMS

Atoms are the basic building blocks of ALL matter in the universe! Atom: Smallest particle of an element that still has all of the properties of that element Atoms are the basic building blocks of ALL matter in the universe!

Element: Single substances that cannot be broken down into simpler substances What are some elements you know?

Compound/Molecule: The chemical combination of two or more elements. Can you think of any other compounds? What elements can you pull out of these compounds?

Chemical Formula vs. Structural Formula Chemical Formula: Each element is represented by its chemical symbol and the number o atoms is shown in its subscripts. Ex. H2O, CO2, CH4, C6H12O6 Structural Formula: shows the chemical symbol of each element and how they are bonded to one another.

Organic vs Inorganic Organic: Usually composed of carbon and hydrogen. “Organic Chemistry” means the study of carbon- containing compounds. Inorganic: They do not contain bonds between carbon atoms

Organic Inorganic C6H12O6 : Sugar C2H6 : Ethane C5H10O5 : Ribose C3H8O3 : Glycerol H2O : Water CO2 : Carbon Dioxide NaCO2- : Sodium Carbonate O2 : Oxygen Water is the most important inorganic compound. Most organisms are 60-90% water by weight.
