uranium
uranium (U), radioactive chemical element of the actinoid series of the periodic table, atomic number 92.Uranium
Uranium is a chemical element; it has symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is a silvery-white metallic chemical element in the periodic table, with atomic number 92. It is assigned the chemical symbol U.
Is uranium the last natural element : – 92) is the last natural element in the periodic table.
Are there only 92 elements
The usual textbook answer is 91. Scientists used to believe that, except for the element technetium, all the elements up to element 92 (uranium) could be found in nature. However, it turns out there are other elements that occur in trace amounts naturally. This brings the number of naturally occurring elements to 98.
What element is 92 and 93 :

| 17 | Chlorine | 93 |
| 18 | Argon | 94 |
| 19 | Potassium | 95 |

Main uranium health effects
Uranium's main target is the kidneys. Kidney damage has been seen in humans and animals after inhaling or ingesting uranium compounds. However, kidney damage has not been consistently found in soldiers who have had uranium metal fragments in their bodies for several years.
Is uranium rare
Uranium is among the more common elements in the earth's crust — about 500 times more common than gold. Although it seems a very rare element, small amounts of uranium are present everywhere — in rock, soil, water, and even our bodies.* Avoid skin contact with Uranium. Wear protective gloves and clothing.ElementXChemical base material which cannot be chemically converted … not or no longer occurring on earth, but artificially generated by nuclear reaction. The artificial elements include the elements technetium (atomic number. Each chemical elemen… Z = 43), promethium (Z = 61) and the tran-suraniums (Z > 92).
118 chemical elements have been identified and named officially by IUPAC.
Do 92 elements occur naturally : The Modern Periodic Table. The modern periodic table includes the 92 naturally occurring elements found in earth's crust and ocean (in green in Fig. 2.7) and two elements, Technetium (Tc) and Promethium (Pm), which are created as byproducts of nuclear reactors (in orange in Fig.
What is the 92 in uranium : Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. U-238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146. Because uranium is radioactive, it is constantly emitting particles and changing into other elements.
Are there 92 natural elements
The usual textbook answer is 91. Scientists used to believe that, except for the element technetium, all the elements up to element 92 (uranium) could be found in nature. However, it turns out there are other elements that occur in trace amounts naturally. This brings the number of naturally occurring elements to 98.
Because uranium decays by alpha particles, external exposure to uranium is not as dangerous as exposure to other radioactive elements because the skin will block the alpha particles. Ingestion of high concentrations of uranium, however, can cause severe health effects, such as cancer of the bone or liver.Based on experimental animal studies, the most likely adverse health effect on humans from ingesting large amounts of uranium is kidney damage.
How much uranium is left : Unconventional resources
Estimates of the amount available range from 9 to 22 million tonnes of uranium, though the 2022 edition of the Red Book tabulates only about 9.3 million tonnes.
