NUCLEAR CHEMISTRY

Atoms are known to undergo certain changes, however, which cannot be explained by changes in the configuration of atomic electrons.

H. Becquerel was the first to notice that a crystal of a salt of uranium placed on a photographic plate in the dark affected the plate so that an image of the crystal appeared. He concluded this effect to have been caused by the emission of some kind of ray from uranium.

Shortly after his discovery, the Curies found the intensity of the rays emitted by the pitchblende ore from which uranium is obtained to be greater than would be expected from a knowledge of the uranium content....

METALS AND NONMETALS

1. There are some distinctions between metals and nonmetals. Metals are distinguished from nonmetals by their high conductivity for heat and electricity, by metallic lustre and by their resistance to electric current. Their use in industry is explained not only by those properties, but also by the fact that their properties, such as strength and hardness, can be greatly improved by alloying them with other metals.
2. There are several important groups of metals and alloys. The common metals such as iron, copper, zinc, etc. are produced in great quantities.
3. The so-called precious metals include silver, gold, platinum and palladium. The light metals are aluminium, berillium and titanium. They are important in aircraft and rocket construction....
