|
Chemical Bond |
A bond that forms when atoms transfer or share electrons. |
|
|
Covalent Bond |
A chemical bond formed by atoms that are sharing one or more electrons. |
|
|
Chemical Formula |
A presentation of a compound that includes the symbols and ratios of atoms of each element in the compound. |
|
|
Ion |
An atom or group of atoms that has an electric charge other than zero, created when an atom or group of atoms gains or loses electrons. |
|
|
Ionic Bond |
A bond that transfers one or more electrons fro 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 atom's valence electrons using dots around the element symbol. |
|
|
Oxidation Number |
A quantity that indicates the charge on an atom when it gains, loses, 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 smaller molecules. |
|
|
Carbohydrates |
A group of energy-rich compounds that are made from carbon, hydrogen, and oxygen that include sugar and 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 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 smaller molecules that are the building blocks of protein. |
|
|
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. |
