Electrons Vocab: 3
Electrons Unit: Concept 3
| Term | Definition |
|---|---|
| Periodic trends | Apecific patterns in the periodic table that make it possible to make predictions about an element's properties |
| Coulomb's law | As the atomic number increases, the nuclear attraction for e- increases, thus pulling the e- more tightly to the nucleus |
| Atomic Radius | One-half the distance between the nuclei of two identical atoms bonded together |
| Reactivity | A measure of how readily an atom will react |
| Shielding effect | When e- in the inner energy levels block the attraction of the nucleus to the valence e- |
| Electronegativity | A measure of the ability of an atom in a bond to attract e- |
| Ionization energy | The energy required to move one e- from a neutral atom of an element |
| Oxidation numbers | The charge of an ion |
| Ionic radius | The radius of a monatomic ion in an ionic compound |
