| If any particle of organic matter falls into a carboy of acid, it is decomposed, and imparts a dark color to the liquid. |
| Ionium expels an alpha particle and becomes radium, which is a bivalent element resembling barium belonging to the second group. |
| He was distinguished, also, as an oculist and aurist, and removed a particle of iron from the cornea by means of a magnet. |
| The particle physics community began adapting existing high-energy accelerators to provide heavy-ion nuclear beams. |
| Thus uranium in the sixth group loses an alpha particle and the product UX1 falls in the fourth group. |
| This stopping power of an atom for an alpha particle is approximately proportional to the square root of its atomic weight. |
