atomic weight

How To Use atomic weight In A Sentence

• There then followed a redetermination of almost all of the other atomic weights arrived at by Stas (with the exception of carbon), and these too, in the majority of cases, were found to require exchanging for more exact values. Nobel Prize in Chemistry 1914 - Presentation
• The equivalent can however be determined very accurately, and we have seen that it is some multiple or submultiple of the true atomic weight. An Elementary Study of Chemistry
• The atomic weight is a ratio quite distinct from the weight in grams.
• Consequently, other atomic weights calculated by reference to oxygen also remained debatable.
• Taking the atomic weight of uranium as 238.5, the atomic weight of ionium should be 230.5, of radium 226.5, of the emanation 222.5, and so on. Ernest Rutherford - Nobel Lecture
• For the next two years, they continued to copublish on the atomic weights of uranium, thorium, and ionium. 86 In addition, their research showed that ionium was not a separate element but just an isotope of thorium. Trafficking Materials and Gendered Experimental Practices: Radium Research in Early 20th Century Vienna
• Radium is an element resembling calcium, strontium, and barium in chemical properties; its atomic weight was determined by Mme. Curie, and found to be about 225, according to her first experiments; a redetermination gave a slightly higher value, which has been confirmed by a further investigation carried out by Sir T.E. Thorpe. Alchemy: Ancient and Modern
• And it is not inconceivable that the still more unstable emanation from the matter named actinium by Debierne and emanium by Giesel may be found to possess an even higher atomic weight than uranium; judging by the phenomenon of brilliant illumination when a preparation of emanium is held above a screen of zinc sulphide, the impression is formed that a very dense matter is falling down on the screen. Sir William Ramsay - Nobel Lecture
• Let it suffice to call to mind how it proved possible to produce from certain thorium minerals lead with precisely the same chemical properties as ordinary lead, but with considerably higher atomic weight - that is to say, an isotope to lead. Nobel Prize in Chemistry 1921 - Presentation Speech
• It is evident, therefore, that the real atomic weight of an element must be some multiple or submultiple of the equivalent; in other words, the equivalent multiplied by 1/2, 1, 2, or 3 will give the atomic weight. An Elementary Study of Chemistry
