The system uranium-lead is very important for radiometric dating of rocks (ages between 106 and 5.109 years).
Uranium
Fishing weights are made of a lead alloy due to its density, malleability, and low cost.Gold and uranium would be better for density, but gold is too expensive and uranium is somewhat hard and brittle (but depleted uranium is somewhat inexpensive although still more expensive than lead).
would you use uranium-lead radiometric dating to finnd an igneous rocks age
Dating rocks age.
Nuclear stations use uranium-235 as the primary fuel element for generating nuclear power. Uranium-235 undergoes fission reactions in a controlled manner to produce heat energy that is then used to generate electricity through turbines.
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-white metal and is primarily known for its use in nuclear power reactors to generate electricity. Uranium is also used in nuclear weapons and has various industrial applications.
lead
The end element of the uranium decay chain is a stable isotope of lead.
Because the uranium dust is inhaled and accumulated in the lungs; long term inhalation of uranium (or uranium compounds, also liquid aerosols) can lead to lungs cancer. Handling a piece of uranium with gloves is not dangerous (excepting of course the irradiated uranium; in this case we use hot cells).
For example lead, sodium, beryllium, uranium, antimony, etc.
To determine the initial number of uranium-238 atoms, we can use the decay relationship between uranium-238 and lead-206. The half-life of uranium-238 is about 4.5 billion years, meaning that after one half-life, half of the uranium-238 would have decayed into lead-206. Since the meteorite now has 78 atoms of lead-206, it suggests that there were originally 78 atoms of lead-206 plus 78 atoms of uranium-238 that decayed to lead-206, totaling 156 atoms of uranium-238 initially.
Characteristics of uranium:When refined, uranium is a silvery white, weakly radioactive metal, which is slightly softer than steel, strongly electropositive and a poor electrical conductor.Uranium is malleable, ductile, and slightly paramagnetic.Uranium metal has very high density, being approximately 70% denser than lead, but slightly less dense than gold.Uranium metal reacts with almost all nonmetallic elements and their compounds, with reactivity increasing with temperature.Hydrochloric and nitric acids dissolve uranium, but nonoxidizing acids attack the element very slowly.When finely divided, it can react with cold water; in air, uranium metal becomes coated with a dark layer of uranium oxide.Uranium in ores is extracted chemically and converted into uranium dioxide or other chemical forms usable in industry.See the link below
