Uranium is radioactive. Which means its nucleus will emitt an alpha particle (two protons and two neutrons) spontaneously. Because the nucleus lost two protons it becomes the element Thorium. Thorium also emitts alpha's and changes to Radium. This process continues; Radium into Radon into Polonium and finally into lead. The final Lead is not radioactive and the process ends. The actual process is a little more complicated because some of these intermediate elements can change by converting a neutron into a proton and emitting an electron (beta radiation), but the basic process is one radioactive element changes into another radioactive element by emitting radiation (alpha's or beta's). The Uranium to Lead Process has a half-life of about 4.5 billion years. Meaning that in 4.5 billion years 1 kilogram of Uranium will have changed to a half kilogram lead and a half kilogram Uranium is still left. This is approximate because there will also be some of those intermediate elements waiting to change.

What radioactive element turns to lead when it has lost lots of energy?

It is uranium that is changed into lead during radioactive decay. Note that there are a number of intermediate steps in the conversion of uranium into stable lead. The uranium does not change directly into lead. The uranium atom undergoes decay, and a radioactive daughter product appears. This continues with radioactive daughters appearing at the end of every step - until lead appears.


Can lead be returned to uranium?

No, lead cannot be converted back into uranium. Once uranium has decayed into lead, it cannot be reversed.


How much lead is in 1 kilogram of pure molten uranium?

Lead is not naturally present in pure uranium. Therefore, there should be no lead in 1 kilogram of pure molten uranium. Lead can be found in trace amounts as impurities in uranium ores, but it is removed during the refining process to obtain pure uranium.


Who in lead with uranium?

Isotopes of lead are the final products of the decay chain of uranium.


Why is lead found in all deposits of uranium ores?

Lead is often found in uranium deposits because they have similar chemical properties and tend to form together during the same geological processes. As uranium ores break down over time, lead is a common byproduct of the radioactive decay of uranium. This is why lead is commonly found in association with uranium deposits.


Is lead heavier than uranium?

Yes, uranium is more dense (heavier) than lead.


Why is lead always present in uranium bearing rocks?

Lead is always present in uranium-bearing rocks because lead is a decay product of uranium. As uranium undergoes radioactive decay, it transforms into different elements, including lead. This is a natural process that occurs over time in the rocks containing uranium.


What does uranium become when its lost its radioactivity?

Uranium becomes lead


What is uranium-lead method?

The uranium-lead method is a radiometric dating technique used to determine the age of rocks and minerals. It relies on the radioactive decay of uranium isotopes to lead isotopes in minerals. By measuring the ratio of uranium to lead in a sample, scientists can calculate the age of the sample.


Why is lead mixed in with all deposits of uranium?

Because the stable isotopes of lead are the end products of the decay chain of uranium natural radioactive isotopes. or because lead is the product of decayed uranium... that should be a good enough answer for your chem teacher you cheater!


What element does uranium-238 end up as?

The decay chain in the uranium 238 series (also called radium series) id lead 206 (stable isotope).


What is the name of the change of state that happens when lead is heated until it turns into a liquid?

The change of state that occurs when lead is heated and turns into a liquid is called melting.
