Similarly, by taking advantage of chemical relationship to the iron group of elements, another body was partially separated by Debierne, to which he gave the name actinium. A Brief Account of Radio-activity

Radium, uranium, thorium, actinium—all the radioactive elements—are, as everybody knows, continually disintegrating, discharging the enormous energy that is imprisoned in their molecules. The Man Who Rocked the Earth

Both independently asked her to provide a precise value for the half-life of the isotope actinium-227, a delicate technical procedure during which she identified the new element. Celebrate the women behind the periodic table 2019-01-27T05:00:00Z

Bodies which contain actinium are particularly rich in emanations. The New Physics and Its Evolution

Further, it became clear from the investigation of uranium minerals that radium, polonium, actinium, and ionium originated from uranium. A Brief Account of Radio-activity

This is true also of the two other elements found in the ores of uranium and thorium, viz., polonium and actinium. Marvels of Modern Science

We may therefore insert provisionally actinium and its series of derivatives between uranium and radium in the radio-active pedigree. Darwin and Modern Science

For if actinium was an independent element we would be sure to find actinium haloes. The Birth-Time of the World and Other Scientific Essays

The same is the case with actinium, which is said to come in the long run from uranium, but not so directly as does radium. The New Physics and Its Evolution

In this class are now placed also the three radio-active gases, emanating respectively from radium, thorium, and actinium. A Brief Account of Radio-activity

Uranium certainly is; thorium—the stuff of this incandescent gas mantle—certainly is; actinium. The World Set Free

What is the final non-active product of the series of changes we have traced from uranium through actinium and radium? Darwin and Modern Science

On Rutherford's theory then, actinium should always accompany uranium and radium, but in very subordinate amount. The Birth-Time of the World and Other Scientific Essays

Since the above was written, another product has been found to intervene between the X substance and the emanation in the case of actinium and thorium. The New Physics and Its Evolution

Curie's discovery of polonium and radium—Their characteristics—Debierne discovers actinium. The New Physics and Its Evolution
