Sentence examples for nobelium from inspiring English sources

Fermium-250 (30-minute half-life), the alpha-decay product of nobelium, was used to ascertain the existence of nobelium-254.

They named it nobelium.

The other new elements discovered by Seaborg were americium (95), curium (96), berkelium (97), californium (98), einsteinium (99), fermium (100), mendelevium (101), nobelium (102), and seaborgium (106).

Of the isotopes of nobelium that have been produced, nobelium-259 (58-minute half-life) is the stablest.

The tripositive state of lawrencium has also been confirmed by a very rapid solvent-exchange experiment in which the lawrencium displayed the behaviour of the tripositive actinoids and not that of the dipositive nobelium or radium, again in accord with the predictions of the actinoid concept.

Subsequent research in the following decade (primarily at Berkeley and Dubna) led the International Union of Pure and Applied Chemistry to conclude that Dubna papers published in 1966 established the existence of the isotope nobelium-254 with an alpha-decay half-life of about 51 seconds.

However, a year later, the Berkeley group working at Lawrence Radiation Laboratory (now known as the Lawrence Berkeley Laboratory) reported that they were unable to reproduce this work, but did create nobelium-254 by bombarding curium-246 with carbon-12 in the new heavy-ion linear accelerator (HILAC; see featured image above the jump).

Its most stable isotope, nobelium-259, has a half-life of approximately 58 minutes.
