We have a no-nonsense approach to test prep and give you access to a large number of practice tests and questions written by test prep professionals.Our practice tests are free and there are no user names to create and no passwords to remember.A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is weakly radioactive because all its isotopes are unstable, with half-lives varying between 159,200 years and 4.5 billion years.Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten.It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. Many contemporary uses of uranium exploit its unique nuclear properties.Historical oddities or anomalous news stories especially attracted my interest, lingering in my mind for years to come.

The events seemed to unfold faster than the news media's ability to keep pace.

Armed with this, you'll be better prepared to tackle tests.

Last month, our free practice tests were taken over 209,000 times and we received 2,450,000 page views from 160,000 unique visitors.

The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99%) and uranium-235 (which has 143 neutrons).

Uranium has the highest atomic weight of the primordially occurring elements.
