Chemistry Formula Quiz: Types of Compounds and Chemical Formulas

Study Notes

Biomolecules

Complex carbohydrates are composed of two or more monomers, including starch, glycogen, cellulose, and chitin.
Proteins are formed by linking together monomers of amino acids.
Nucleic acids are made by linking sequences of monomers called nucleotides, including DNA and RNA.

Atomic Structure

Atomic structure consists of three subatomic particles: protons (positive), neutrons (uncharged), and electrons (negative).
Atomic number is the number of protons in an atom's nucleus, which determines the chemical element in the periodic system.

Isotopes and Elements

Isotopes are forms of an element having the same atomic number but different mass number.
Each atom has an equal number of positively charged protons inside its nucleus and negatively charged electrons outside its nucleus, but they have different numbers of uncharged neutrons.

Compounds

Organic compounds contain at least two carbon atoms combined with each other and with atoms of one or more other elements (e.g., H, O, N, S, P, Cl, Fl).
Inorganic compounds lack carbon-hydrogen bonds and may consist of heavy metals and toxic elements (e.g., lead, mercury, chromium, arsenic, etc.).

Chemical Formula

Chemical formula shows the number of atoms (ions) of each type of compound (e.g., H2O, O2, O3, N2, N2O, H2S, NH3, H2SO4, CH4, C6H12O6).

Types of Organic Compounds

Hydrocarbons are compounds of carbon and hydrogen atoms (e.g., methane).
Chlorinated hydrocarbons are compounds of carbon, hydrogen, and chlorine atoms (e.g., pesticide DDT, chloroform).
Simple carbohydrates are simple sugars, consisting of compounds of carbon, hydrogen, and oxygen atoms (e.g., glucose).
Organic polymers are larger and more complex organic compounds consisting of a number of basic structural or molecular units called monomers linked by chemical bonds.

Description

Test your knowledge on the two types of compounds, organic and inorganic, and learn about chemical formulas used by chemists to represent compounds. Explore examples like water (H2O) and carbon dioxide (CO2) in this quiz.
