IHS Periodic table terms
| Question | Answer |
|---|---|
| Insulator | A material that does not conduct electricity (electric insulator) or heat (thermal insulator); a solid in which the conduction band is not populated and the gap between the valence and conduction bands is greater than about 10 electron volts |
| Anion | Negatively charged ions formed by nonmetals that take electrons from other atoms, causing them to have one or more additional electrons relative to the number of protons in the nucleus. |
| Noble Gases | A group of gaseous elements which make up group 18 of the periodic table. The molecules of these gases are monatomic, i.e., they exist as isolated atoms. All these gases are chemically unreactive and are not readily ionized. These features arise because t |
| p-orbital | An atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. |
| Cation | A positively charged ion that migrates naturally to a cathode |
| Ionization | Ionization is the physical process of converting an atom or molecule into an ion by adding or removing charged particles such as electrons or other ions. This is often confused with dissociation (chemistry) |
