| Term | Definition |
|---|---|
| Atom | The smallest particle an element can be divided into and still be the same substance |
| Atomic Number | The number of protons contained in the nucleus of an atom |
| Bond | A strong force of attraction holding atoms together in a substance |
| Compound | A substance containing two or more elements chemically bonded together |
| Covalent Bond | Chemical bond that involves the sharing of electron pairs between atoms |
| Density | A measure of the mass of a defined volume of water |
| Electron | A negatively charged subatomic particle that orbits the nucleus of an atom |
| Element | a substance that cannot be chemically broken down into a similar substance |
| Emergent Properties | Characteristics that are present within a compound or molecule of two or more different elements that those elements do not possess on their own |
| Gradient | The rate of change in the y-axis value has the x-value increases |
| Hydrogen Bond | A weak bond between two molecules due to the electrostatic attraction between a hydrogen atom in one molecule and an atom of oxygen, nitrogen or fluorine in the other molecule |
| Ion | An atom or molecule that has lost or gained one or more electrons, creating an electrical charge |
| Ionic Bond | Chemical bond that involves the attraction between two oppositely charged ions |
| Kinetic Particle Theory (particle theory) | The theory of how particles (such as atoms and molecules) move in relation to each other and the amount of energy within the system |
| Molecule | A group of atoms covalently bonded together |
| Neutron | Neutral subatomic particles contained within the nucleus of an atom |
| Nucleus (atom) | The positively charged center core of an atom that is made of protons and neutrons |
| Polar | When opposite sides of a molecule have contrasting (partial) electrical charges |
| Principle of Constant Proportions | The ratio of any two major ions dissolved in seawater is constant |
| Proton | A positively charged subatomic particle contained within the nucleus of an atom |
| Pycnocline | A layer of water between two layers of water with different densities |
| Shells | Each of a set of orbitals around the nucleus of an atom that can be occupied by electrons |
| Solvent | A substance which is able to dissolve other substances |
| Specific heat capacity | The heat required to raise the temperature of the unit mass of a given substance by one degree Celsius |
| Thermal Insulator | A substance which reduces the rate of transfer of thermal energy |
| Water Collumn | A vertical section of water from the surface to the bottom; useful concept when discussing changes in the abiotic factors within the body of water |
| Water Vapour | Gaseous phase/state of water; produced when liquid water evaporates or boils |
