A stack we had to create for a homework assignment.
| Term | Definition |
|---|---|
| Model | A representation of something in any form. |
| Atom | The basic building block of the entire universe. |
| Nucleus | The center of something, in this case an atom. |
| Proton | A subatomic particle with a positive charge. |
| Neutron | A subatomic particle with a neutral charge. |
| Electron | A subatomic particle with a negative charge. |
| Atomic Number | The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table. |
| Atomic Symbol | The atomic number of an element determines its position in the Periodic Table. |
| Subatomic Particle | A particle/entity smaller than a atom. |
| Molecule | A combination of two or more atoms. |
| Lewis Structures | Lewis structures are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. |
| Bohr Model | A simple definition of Bohr's atomic model is: electrons orbit the nucleus at set distances. |
| Electron Shell | The electrons in the outermost occupied shell (or shells) determine the chemical properties of the atom; it is called the valence shell. |
| Valence Electron | A valence electron is an electron that is associated with an atom, and that can participate in the formation of a chemical bond. |
| Matter | The state of an object. It can be either liquid, gas, or solid. |
