| Aqueous Solution | A solution in which the water is the solvent.
🗑
|
||||
| Atom | The smallest unit of matter that retains the properties of an element.
🗑
|

| Base | A substance that decreases the hydrogen ion (H+) concentration in a solution.
🗑

| Chemical Reaction | A process leading to chemical changes in matter, involving the making and/or breaking of chemical bonds.
🗑
|
||||
| Cohesion | The attraction between molecules of the same king
🗑
|
||||
| Compound | A substance containing 2 or more elements in a fixed ratio.
🗑
|
||||
| Covalent Bond | An attraction between atoms that share 1 or more pairs of outer-shell electrons.
🗑
|
||||
| Electron | A subatomic particle with a single unit of negative electrical charge. One or more electrons more around the nucleus of an atom.
🗑
|
||||
| Element | A substance that cannot be broken down to other substance by chemical means.
🗑
|
||||
| Hydrogen Bond | A type of Weak chemical bond formed when the partially positive hydrogen atom participation in a polar covalent bond in another molecule (or in another part of the same macro molecule)
🗑
|
||||
| Ion | An atom or molecule that has gained or lost one or more electons thus acquiring an electrical charge
🗑
|
||||
| Ionic bond | An attraction between two ions with opposite electrical charges the electrical attraction of the opposite charges holds the ions together.
🗑
