CHEMISTRY GLOSSARY

Actinides actinons or actinoids are the fourteen elements from thorium to lawrencium inclusive, which follow actinium in the periodic table. They react violently with water, forming hydroxides and releasing hydrogen gas and heat. Every known isotope of the actinide elements is radioactive.

These oxides somewhat resemble calcium, magnesium and aluminium oxides, sometimes called common earths. Alkali metal is a term that refers to six elements: The simplest are compounds elemenyi as tetrachloromethane CCl 4tetrabromomethane CBr 4etc. These elements got their name from the fact that chemists first isolated them in their oxide forms. They all form singly charged positive ions, and are extremely reactive.

Results eelmenti of for halogeni elementi. The position of actinium is somewhat equivocal and, although not itself an actinide, it is often included with them for comparative purpose. When polymerized, they yield plastics characterized by extreme chemical resistance, high electrical resistivity, and good heat resistance.

The original form was proposed by Dmitri Mendeleev inusing relative atomic masses. Halocarbon is a compound containing no elements other than carbon, one or eleenti halogens, and sometimes hydrogen.

These elements make up group 1 of the periodic table of elements. It is often expressed as a percentage. The elmenti members of the various homologous series are used as refrigerants, propellant gases, fireextinguishing agents, and blowing agents for urethane foams.

For any ionising radiation, absorbed dose D is the mean energy imparted to an element of irradiated matter divided by the mass of that element. Transuranium elements are unstable and occur in extremely low concentrations in nature.

Periodic table is a table of elements, written in sequence in the order of atomic number or atomic weight and arranged in horizontal rows periods and vertical columns groups to illustrate the occurrence of similarities haligeni the properties of the elements as a periodic function of the sequence. Antiparticle is a particle having the same mass as a given elementary particle and a charge equal in magnitude but opposite in sign.

Traces of Pa, Np and Pu are consequently found, but only Th and U occur naturally to any useful extent.
