According to theLos Alamos National Laboratory, Klaproth named the new element after the recently discovered planet Uranus, which was named for the Greek god of the sky. Eugène-Melchior Péligot, a French chemist, isolated pure uranium in 1841 by heating uranium tetrachloride with potassium. Uran...

Why was neptunium, named for the planet Neptune, a good name for element 93? Because it comes after uranium, which was named after the planet Uranus. Because it is found in the ocean. Because it is only found on the planet Neptune. Because it is radioactive. Next Worksheet Print Wo...
(Uranium, the element before neptunium, had been named for the planet Uranus.) Physical and chemical properties Neptunium is a silvery white metal with a melting point of 640°C (1,180°F) and a density of 20.45 grams per cubic centimeter. Chemical properties Neptunium is fairly ...
The two elements just before plutonium in the periodic table had also been named for planets: uranium for Uranus and neptunium for Neptune. Glenn Seaborg later went on to find a number of other elements. One of those elements, atomic number 106, has been named seaborgium in his honor. ...
Element 93 is named after the planet Neptune whose discovery followed that of the planet Uranus. Neptunium, atomic number 93, was discovered in the form of the isotope 239Np (t 1/2 = 2.6 d) by E.M. McMillan and P.H. Abelson in 1940 from neutron capture by 238U followed by the ...
