Question

Why does uranium have the number $92$?

Answer 1

Uranium has an atomic quantity of thanks to this that there are protons and electrons withinside the atomic shape due to the very fact uranium is radioactive, its miles continuously emitting debris and converting into different elements.

Complete Answer:
Uranium may be a chemical detail with the image U and atomic quantity. It’s silvery-gray steel withinside the actinide collection of the table. A uranium atom has protons and electrons, of which 6 are valence electrons. Uranium is weakly radioactive thanks to the very fact all isotopes of uranium are unstable; the half-lives of its happening isotopes variety among $159$, two hundred years, and $4.5$billion years. The utmost commonplace place isotopes in herbal uranium are uranium-$238$ (which has $146$neutrons and debts for over $99\%$of uranium on Earth) and uranium-$235$ (which has 143 neutrons). Uranium has the absolute best relative atomic mass of the primordially happening elements. Its density is prepared $70\%$ better than that of lead, and barely decreases than that of gold or tungsten. It happens clearly in low concentrations of some elements consistent with million in soils, rock, and water, and is commercially extracted from uranium-bearing minerals including uraninite.

Note:
Depleted uranium is likewise used as a protecting fabric during a few packing containers wont to shop and shipping radioactive materials. While the steel itself is radioactive, its excessive density makes it extra powerful than lead in halting radiation from robust reasserts including radium. Others make use of depleted uranium encompass counterweights for plane manipulate surfaces, as ballast for missile re-access cars, and as a protecting fabric.
