Kinetic Energy |
Energy in motion |
|
|
Proton |
subatomic particle occurring in all atomic nuclei, with a positive electric charge |
|
|
Atomic Nucleus |
small, dense region consisting of protons and neutrons at the center of an atom, orbited by electrons |
|
|
Potential Energy |
Energy at rest |
|
|
Neutron |
subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen |
|
|
Temperature |
A measure of the intensity of heat, reflecting the average kinetic energy or speed of molecules |
|
|
Electron |
stable subatomic particle with a negative charge, found in all atoms and acting as the primary carrier of electricity in solids. |
|
|
Chemistry |
The science concerned with the study of the composition, structure, and properties of matter, and the changes it undergoes |
|
|
Atomic number |
The number of protons in each atom of a particular element |
|
|
Chemical bond |
An attraction between two or more atoms resulting from a sharing of valence electrons, or the presence of opposite charges of atoms |
|
|
Formula |
Refers to what elements are contained in a chemical bond, and in What proportion |

|
Heat |
Amount of kinetic energy contained in the movement of atoms and molecules in a body of matter |
|
|
Solution, solvent, solute |
Coffee-water-sugar. A solution is a liquid consisting of a homogeneous mixture of two or more substances created when a solvent dissolves a solute |

Solution |
A liquid consisting of a homogeneous mixture of two or more substances |
|
|
Buffer |
A chemical substance that resists change in pH by accepting H+ ions, or donating H+ ions, to a solution |
|
|
Hydrolysis |
Process or reactions that occur when large molecules are broken down by water |
|
|
Product |
An ending material in a chemical reaction |
|
|
Ionic bond |
An attraction between two ions with opposite electrical charges. Na+Cl- Mg+2Cl2-2 |

|
Isotope |
An element that has the same number of protons and electrons but a different number of neutrons |
|
|
Dehydration synthesis |
A reaction in which a glucose molecule loses an OH and a fructose molecule loses a H resulting in sucrose and water |
