It is well known that Pierre and Marie Curie used this new-found radioactivity to identify the new elements polonium and radium.
Curie gave the name of polonium for Poland, her native land.
Discovery ofPolonium Following up this supposition, M.
In some cases the chemical action was determined and these new bodies were found analogous to well-known elements, as radium to barium, polonium to bismuth.
Footnote 35: It has now been shown that polonium when freshly separated emits beta rays also; see Dr Logeman's paper in Proceedings of the Royal Society, A.
Two other bodies, poloniumand actinium, the one characterised by the special nature of the radiations it emits and the other by a particular spectrum, seem likewise to exist in pitchblende.
Footnote 33: Polonium has now been shown to be no new element, but one of the transformation products of radium.
Curie's discovery of poloniumand radium--Their characteristics--Debierne discovers actinium.
Nor have they the same chemical affinities; polonium belongs to the bismuth group, radium to the barium and actinium to the titanium series.
Analogous experiments were carried on with the specimens from Paris, but they were only one fifth as strong in effects; that labelled 'polonium sub-nitrate' had positively no action on the plates used.
We can tell how the elements of high atomic weight, such as uranium and thorium, are constantly giving off particles and are thus by loss or decomposition being changed over into other elements, such as radium, niton, polonium and lead.
While these rays were comparable with those observed from polonium and radium, the chemical properties are entirely different from those of these substances.
Madame Curie, examining the different substances in pitchblende, found among them two new radiant substances, both more active than uranium, which they called polonium and radium.
Polonium was found to be closely akin to bismuth, accompanying that metal in all its reactions, but separable from it by fractionation.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "polonium" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: element; gold; iron; lead; metal; radium; silver
