you have to give it 6 valence electrons
All the isotopes of uranium (natural or artificial) are radioactive and unstable.
Uranium is unstable, radioactive element.
Similar to all other chemical elements the uranium atom has protons, neutrons and electrons; uranium is also unstable and radioactive.
Uranium 235 is unstable because it is a radioactive isotope. This means that it is constantly decaying and emitting radiation. The reason it is unstable is because it has too many neutrons in its nucleus. The neutron is a unstable particle, and when there are too many of them in one place, they can cause problems. When uranium 235 decays, it emits alpha particles, which are high-energy particles that can damage DNA and cause cancer.
Uranium valences: 3,4,5,6,7, possible also 2 in the unstable oxide UO.
Uranium is considered a radioactive chemical element because uranium (all the isotopes) is unstable and emit nuclear radiations.
Similar to all other chemical elements the uranium atom has protons, neutrons and electrons; uranium is also unstable and radioactive. Potters use uranium in their gaze to get a rich yellow colour.
none, uranium itself is unstable, there are no stable elements after bismuth; and even some researchers suggest that bismuth is an unstable radioactive element with a halflife approaching twice the age of the universe.
Uranium has an atomic weight greater than iron and is more unstable.
Actinium is separated from pitchblende. Actinium, AC, is found in uranium ore, a product of radioactive decay of uranium and ?æother unstable elements.
Uranium valences: 2, 3, 4, 5, 6; the valence two is possible only in the unstable oxide UO.
All the isotopes of uranium are radioactive and unstable.
