| Term | Definition |
|---|---|
| Element | A part or aspect of something abstract especially one that is essential or characteristic |
| Compound | a thing that as composed of two or more separate elements; a mixture. |
| Atomic | The total mass of an atom, primarily determined by the sum of protons and neutrons in its nuclear. |
| Electrons | A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids. |
| Neutrons | A subatomic particle of about the same mass as a proton but without an electric charge, presents in all atomic nuclei except those of ordinary hydrogen. |
| Protons | A stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign. |
| Electron cloud | The visual representation of the probable locations of electrons surrounding an atoms nucleus, representing the region of negative charge. |
| Valence electron | The negatively charged subatomic particles located in the outermost electron shell (valence shell) of an atom. |
| Electron Dot | A visual representation of an atom's valence electrons outermost electrons as dots placed around its chemical symbol, showing how these electrons are arranged and used in chemical bonding, often aiming for a stable octet (eight electrons). |
| Bohr Model | A model of the atom that depicts electrons orbiting a small, positively charged nucleus in specific, fixed circular parts called orbits or shells each with a quantized energy level. |
