| Question | Answer |
|---|---|
| Matter | Anything that occupies space and has mass |
| Molecule | Particles of matter made up of one or more atoms |
| Atoms | A unit of energy made up of protons, neutrons, and electrons |
| Proton | A particle with a positive charge; in the nucleus |
| Neutron | A particle with a neutral charge; in the nucleus |
| Electron | A particle with a negative charge; orbits the nucleus |
| Element | A substance composed of a single type of atom |
| Compound | A substance composed of different types of atoms |
| Ionic Bond | Electron donating between atoms to fill or empty shells |
| Covalent Bond | Electron sharing between atoms |
| Covalent Bond | Most stable bond |
| Polar Covalent Bond | Electrically neutral; positive side of a molecule attracts negative side of another molecule |
| Organic Compounds | Contain hydrogen and carbon atoms |
| Inorganic Compounds | Do NOT contain hydrogen or carbon atoms |
| Hydrolysis | Bond breaking of large molecules via water into smaller molecules (catabolism) |
| Dehydration Synthesis | Water is removed from reactants |
| Energy | The capacity to work |
| Potential Energy | Energy due to position |
| Kinetic Energy | Energy due to the motion of an object |
| Metabolism | The physiological process of converting food and air into energy |
| Anabolism | Chemical reactions causing the formatin of complex compounds from simple molecules |
| Catabolism | Chemical reactions causing complex compounds to break down and release energy |
| Enzymes | Proteins that catalyze or speed up chemical reactions without being consumed or altered in the process |
| pH | A measure of hydrogen ion concentration in a sample |
| Neutral pH | 7 |
| Acidic pH | below 7; MORE hydrogen ions |
| Alkaline pH | above 7; LESS hydrogen ions |
