what is uranium on the periodic table?
10849
Uranium (U), radioactive chemical element of the actinoid series of the periodic table, atomic number 92. It is an important nuclear fuel.

Uranium ore deposits are economically recoverable concentrations of uranium within the Earth's crust. Uranium is one of the more common elements in the Earth's crust, being 40 times more common than silver and 500 times more common than gold. It can be found almost everywhere in rock, soil, rivers, and oceans.

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. ... The columns, called groups, contain elements with similar chemical behaviours.

How many protons, neutrons, and electrons are there in an atom of uranium-238? Write the symbol for this isotope. The atomic number of uranium (see periodic table) is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 238 — 92 : 146 neutrons.

transuranic elements (transuranium elements) Elements with atomic numbers higher than that of uranium (92), the best known of which are members of the actinide series (atomic numbers 89 to 103). All transuranic elements are radioactive.

The actinides are elements 89 to 103 and fill their 5f sublevel progressively. Actinides are typical metals and have properties of both the d-block and the f-block elements, but they are also radioactive.

Actinides are the 15 elements with atomic numbers from 89 to 103. They are named after the first element in the series, actinium. The actinides group includes mostly man-made elements with only a few exceptions such as uranium and thorium.

Uranium is an abundant metal and is full of energy: One uranium fuel pellet creates as much energy as one ton of coal, 149 gallons of oil or 17,000 cubic feet of natural gas. It does not come out of the ground ready to go into a reactor, though.

Uranium atoms have 92 electrons and the shell structure is 2.8. 18.32. 21.9.

Ununtrium (Uut). Diagram of the nuclear composition, electron configuration, chemical data, and valence (outer electron) orbitals of an atom of ununtrium-284 (atomic number: 113), an isotope of this radioactive element. The nucleus consists of 113 protons (red) and 171 neutrons (orange).

Characteristics: Uranium is a dense, silvery-white, slightly paramagnetic, radioactive metal. It is also ductile and malleable. The metal tarnishes in air acquiring a dark layer of oxide.

Nuclear fuel—uranium Uranium is the fuel most widely used by nuclear plants for nuclear fission. ... Nuclear power plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare.

Uranium was discovered in 1789 by Martin Klaproth, a German chemist, in the mineral called pitchblende. It was named after the planet Uranus, which had been discovered eight years earlier.
