Radium \Ra`di*um\, n. [NL., fr. L. radius ray.] (Chem.)       An intensely radioactive metallic element found (combined) in       minute quantities in pitchblende, and various other uranium       minerals. Symbol, Ra; atomic weight, 226.4. Radium was       discovered by M. and Mme. Curie, of Paris, who in 1902       separated compounds of it by a tedious process from       pitchblende. Its compounds color flames carmine and give a       characteristic spectrum. It resembles barium chemically.       Radium preparations are remarkable for maintaining themselves       at a higher temperature than their surroundings, and for       their radiations, which are of three kinds: alpha rays, beta       rays, and gamma rays (see these terms). By reason of these       rays they ionize gases, affect photographic plates, cause       sores on the skin, and produce many other striking effects.       Their degree of activity depends on the proportion of radium       present, but not on its state of chemical combination or on       external conditions.The radioactivity of radium is therefore       an atomic property, and is explained as result from a       disintegration of the atom. This breaking up occurs in at       least seven stages; the successive main products have been       studied and are called          {radium emanation} or exradio,          {radium A},          {radium B},          {radium C}, etc. (The emanation is a heavy gas, the later             products are solids.) These products are regarded as             unstable elements, each with an atomic weight a little             lower than its predecessor. It is possible that lead is             the stable end product. At the same time the light gas             helium is formed; it probably consists of the expelled             alpha particles. The heat effect mentioned above is             ascribed to the impacts of these particles. Radium, in             turn, is believed to be formed indirectly by an             immeasurably slow disintegration of uranium.

Ride originally meant (and is so used                   throughout the English Bible) to be carried on                   horseback or in a vehicle of any kind.

Johnson seems to sanction this distinction by                   giving [bd]to travel on horseback[b8] as the leading                   sense of ride; though he adds [bd]to travel in a                   vehicle[b8] as a secondary sense. This latter use of                   the word still occurs to some extent; as, the queen                   rides to Parliament in her coach of state; to ride in                   an omnibus.                               [bd]Will you ride over or drive?[b8] said Lord                            Willowby to his quest, after breakfast that                            morning.                                       --W.
