What is seaborgium made of?
Source: Seaborgium is a synthetic, radioactive metal, created by nuclear bombardment. It has only been produced in tiny amounts. The metal is made by bombarding californium-249 with heavy oxygen ions. Isotopes: Seaborgium has 11 isotopes whose half-lives are known, with mass numbers from 258 to 271.

Is seaborgium an element?
What element is most like seaborgium?
Both our isothermal gas chromatographic and liquid chromatographic separations clearly indicate that seaborgium behaves similarly to its lighter homologues molybdenum and tungsten, and its behaviour is typical for a group 6 element of the period table.
What is the main use of promethium?
The radioactive decay of promethium is used to make a phosphor give off light and this light is converted into electricity by a solar cell. Promethium can also be used as a source of x-rays and radioactivity in measuring instruments.
What are 3 uses of promethium?
Most promethium is used for research purpose. It can be used as beta radiation source in luminous paint, in nuclear batteries for guided missiles, watches, pacemakers and rados, and as a light source for signals. It is possible that in future it will be used as portable X-ray source.
What is the element seaborgium used for?
Since only a few atoms of seaborgium have ever been made, there are currently no uses for seaborgium outside of basic scientific research.
What physical property is holmium known for?
Physical properties Like other rare earth elements, holmium is a silvery metal that is soft, ductile, and malleable. Ductile means capable of being drawn into thin wires. Malleable means capable of being hammered into thin sheets. Both properties are common for metals.
What type of element is holmium?
Holmium (Ho), chemical element, a rare-earth metal of the lanthanide series of the periodic table.
Where is seaborgium on the periodic table?
seaborgium (Sg), an artificially produced radioactive element in Group VIb of the periodic table, atomic number 106. In June 1974, Georgy N. Flerov of the Joint Institute for Nuclear Research at Dubna, Russia, U.S.S.R. , announced that his team of investigators had synthesized and identified element 106.
What family does element seaborgium belong to?
The elemental classification of Seaborgium is Transition metals, and it belongs to group 6 and period 7 in the Periodic Table of Elements. Seaborgium was discovered in the year 1974 by Lawrence Berkeley National Laboratory.
What does seaborgium look like?
Seaborgium is an artificially produced radioactive chemical element, it’s appearance is unknown, it probably has a silvery white or metallic gray colour. The most stable isotope Sg 271 has an half life of 2.4 minutes.
What are uses for seaborgium?
Uses of Seaborgium: At this time, the only use of seaborgium is for research, primarily toward the synthesis of heavier elements and to learn about its chemical and physical properties. It is of particular interest to fusion research.
What does seaborgium mean?
Seaborgium is a transuranium element. This means that it is “beyond” (trans) the element Uranium in the sequence of elements. Mendeleev predicted that Seaborgium would exist. He called the element eka-tungsten because of its location was near Tungsten in the Periodic Table . The chemistry of seaborgium is like the chemistry of tungsten .
