# of protons = # of electrons (+ charge) (- charge)
Atoms Atoms are neutral # of protons = # of electrons (+ charge) (- charge)
5
ATOMS
6
Element A chemical element is a pure substance that consists entirely of one type of atom. There are more than 100 elements, but only a few are commonly found in living organisms. What does C,H,O,N stand for?
8
What does C H O N stand for?
Carbon Hydrogen Oxygen Nitrogen
9
Compounds A chemical compound is a substance formed by the chemical combination of 2 or more elements Name 3 compounds…

HOMEWORK
15
They might be giants “Meet the Elements
16
Chemical Formulas Prefix Meaning Uni- Mono- One Bi- Di- Two Poly- Many
17
Let’s practice C Co CO An upper case letters symbolizes one element.
An upper case letter next to a lower case letter symbolizes one element. An upper case letter next to another upper case letter symbolizes two elements.
18
Element vs. compound Which of the following are elements and which are compound?
Na NO2 Element Compound
19
Naming compounds CO Carbon monoxide CO2 Carbon dioxide
Use the name of the element and a prefix to indicate the number of atoms. CO Carbon monoxide CO2 Carbon dioxide
20
Let’s practice… H2O C6H12O6 Name the following: NaCl HCl
Write the chemical formula: water glucose Sodium Chloride Hydrochloric Acid H2O C6H12O6
21
Equations Equations are used to describe chemical reactions
The substances that start the reaction are called reactants The substances formed by the reaction are called products The arrow means “to make” or “to form”
22
This is the chemical equation for:
Cellular Respiration Reactants products C6H12O6 + O2 CO2 + H2O + Energy
23
Chemical equations
24
Organic vs. Inorganic Compounds Living things are made up of organic and inorganic compounds
Inorganic compounds do not contain BOTH carbon and hydrogen Water Salts Inorganic acids Bases Carbon dioxide Oxygen Organic compounds contain BOTH carbon and hydrogen Carbohydrates Proteins Lipids Nucleic acids
25
ORGANIC COMPOUNDS FLIP BOOK
