actiniumadsorptionbehaviorcationscesiumcesium chlorideschemicalsfranciumThe present paper concerns a generalization of work on the chemistry of francium carried out by means of Fr 212. Methods for recovery and isolation of francium isotopes are considered. Co-precipitation of Fr 212 with various ...
Thus a course of lectures on radioactivity and isotopy has been omitted, because these subjects are dealt with in existing books by the author and others; but one of the most interesting of current problems is discussed fully in a chapter on the origin of actinium. The conclusion is drawn ...
The element has properties similar to those of lanthanum. Generally speaking, elements in the same column in the periodic table have similar properties. Few compounds of actinium have been produced. Neither the element nor its compounds have any important uses. ...
It becomes superconductive below 2 271.8℃ (1.4K). Its melting point of 1750℃ is above both those of actinium (1227℃) and protactinium (1568℃). At the start of period 7, from francium to thorium, the melting points of the elements increase (as in other periods), because the number...

Properties:Radon has a melting point of -71°C, boiling point of -61.8 °C, gas density of 9.73 g/l, specific gravity of the liquid state of 4.4 at -62°C, specific gravity of the solid state of 4, usually with a valence of 0 (it does form some compounds, however, such as rado...
Physical properties Enough americium has been produced to determine a few of its properties. It is a silvery-white metal with a melting point of about 1,175°C (2,150°F) and a density of about 13.6 grams per cubic centimeter. A number of its compounds have been produced and studied,...
