|
Chemical Bond |
a bond that forms when atoms transfer or share electrons. |
|
|
Covalent Bonds |
a chemical bond formed by atoms that are sharing one or more electrons. |
|
|
Chemical Formula |
a representation of a compound that includes the symbols and ratios of atoms of each element in the compound. |
|
|
Ion |
an atom that has an electric charge other than zero, created when an atom gains or loses electrons. |
|
|
Ionic Bond |
a bond that transfers one or more electrons from one atom to another, resulting in attraction between oppositely charged ions. |
|
|
Valence Electrons |
the electrons in the highest, unfilled energy level of an atom. |
|
|
Lewis Dot Diagram |
a method for representing an atoms valence electrons using dots around the element symbol. |
|
|
Oxidation Number |
a quantity that indicates the charge on an atom when it gains, or shares electrons during bond formation. |
|
|
Binary Compound |
a chemical compound that consists of two elements. |
|
|
Polyatomic Ion |
an ion that contains more than one atom. |
|
|
Organic Chemistry |
a branch of chemistry that specializes in the study of carbon compounds, also known as organic molecules. |
|
|
Polymer |
a compound that is composed of long chains of similar molecules. |
|
|
Carbohydrades |
a group of energy rich compounds that are made from Carbon, Hydrogen, and Oxygen and that include sugars ant starches. |
|
|
Lipids |
a group of energy rich compounds that are made from Carbon, Hydrogen, and Oxygen and that include fats, waxes, and oils. |
|
|
Saturated Fat |
a fat in which the Carbon atoms are surrounded by as many Hydrogen atoms as possible. |
|
|
Unsaturated Fat |
a fat that has fewer Hydrogen atoms because double bonds exist among some of the Carbon atoms. |
|
|
Proteins |
a group of very large molecules made up of Carbon, Hydrogen, Oxygen, Nitrogen, and sometimes Sulfur. |
|
|
Enzyme |
a type of protein used to speed up chemical reactions in living things. |
|
|
Amino Acids |
a group of similar molecules that are the building blocks of proteins. |
|
|
Nucleic Acids |
compounds made of long, repeating chains of smaller molecules called nucleotides. |
|
|
DNA |
a type of nucleic acid that contains the genetic code for an organism. |
