He called this new element eka-silicon, after observing a gap in the periodic table between silicon and tin: similarly, mendeleev discovered gallium ( eka -aluminum) and scandium ( eka -boron) on paper, because he predicted their existence and their properties before their actual discoveries.
Astronomers using the nasa/esa hubble space telescope have detected helium in the atmosphere of the exoplanet wasp-107b this is the first time this element has been detected in the atmosphere of a planet outside the solar system.

On the one hand these properties make helium-4 a most useful element, for example in cryogenics, but on the other, it poses severe tests for theoretical models the purpose of this paper is to describe in detail the algebraic surface mthat should. The us has been selling off its helium reserve, established in the 1920s to provide gas for airships - but even so, shortages have been occurring some scientists believe a finite resource that. While selenium is not a metallic element, gray selenium is a good photoconductor, and was used in early photocells subsequently, selenium and various selenium compounds have been used in a variety of photoconductor and photovoltaic applications.
