Seaborgium is a synthetic chemical element with the symbol Sg and atomic number 106. As a synthetic element, it can be created in a laboratory but is not found in nature. It is also radioactive; the most stable known isotope, 269Sg, has a half-life of approximately 14 minutes.

Uses of Darmstadtium Presently, there are no uses or applications of Darmstadtium. It is only used for research purposes. Biological use is yet to be known.

Uses of Roentgenium: The only uses of roentgenium are for scientific study, to learn more about its properties, and for the production of heavier elements. Roentgenium Sources: Like most heavy, radioactive elements, roentgenium may be produced by fusing two atomic nuclei or via decay of an even heavier element.

Hassium’s most stable isotope, hassium-270, has a half-life of about 22 seconds. It decays into seaborgium-266 through alpha decay.

Seaborgium is harmful due to its radioactivity. Characteristics: Seaborgium is a radioactive synthetic metal and has only been produced in tiny amounts.

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.

Seaborgium has an atomic number of 106, so it therefore has 106 protons in its nucleus. It’s atomic mass is 269 AMU. This occurs when the element is unstable due to the fact that the nucleus can no longer hold its particles together. The most recently made seaborgium has a half-life of 0.8 seconds.

The name seaborgium was chosen to honor the man who shared the 1951 Nobel Prize in chemistry with former LBL Director Edwin McMillan for “their discoveries in the chemistry of the transuranium elements.” Born in 1912 in Ishpeming, Michigan, Seaborg received a Ph. D.

The elements of the periodic table sorted by atomic mass

As only a little seaborgium ever been made, its reactivity with air is unknown. One would predict its behaviour to be similar to that of tungsten (immediately above seaborgium in the periodic table) and molybdenum (two places above).

Gold is one of the least reactive elements on the Periodic Table. It doesn’t react with oxygen, so it never rusts or corrodes. Gold is unaffected by air, water, alkalis and all acids except aqua regia (a mixture of hydrochloric acid and nitric acid) which can dissolve gold. Gold does react with halogens.

Because it is so “anxious” to pull another electron into its orbit, chlorine is an extremely reactive element. In contrast, argon, sitting next to chlorine on the Periodic Table of the Elements, is very stable as a single atom because it has a full outer orbit of eight electrons.

Chlorine also has a multitude of industrial uses. Including making bulk materials like bleached paper products, plastics such as PVC and the solvents tetrachloromethane, chloroform and dichloromethane. It is also used to make dyes, textiles, medicines, antiseptics, insecticides and paints.

Although both chlorine and phosphorus are very reactive elements, chlorine is more reactive than phosphorus. Reason behind this is more electronegativity due to which can easily accept electrons to form bonding with other elements.

Halogens are considered the most reactive elements. And in order to complete their octet they react with the alkali metals. It is considered more reactive than sulphur because chlorine loses one electron to complete its outer most shell while sulphur loses two electron which make it less reactive than chlorine.

Less reactive metals react with acids and oxygen, but not water, and include several transition metals such as zinc, iron, and tin.

The primary difference between metals is the ease with which they undergo chemical reactions. The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive.

Sodium and Potassium are highly reactive metals and react vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn’t react with kerosene.

If it is kept in open air, it easily reacts with the oxygen and catches fire. Since kerosene is a mixture of hydrocarbons, it won’t react with it.

Phosphorus is a very reactive non-metal. It catches fire if exposed to air. To prevent the contact of phosphorus with atmospheric oxygen, it is stored in water.

Sodium is a very reactive element, so it reduces oxygen and water by being an effective reduction agent. Therefore with kerosene oil, Na does not show any reaction. Sodium should not be preserved in water, since sodium and water interactions are extremely exothermic.
