Which is an example of a parent isotope?

A parent isotope is one that undergoes decay to form a daughter isotope. One example of this is uranium (atomic number 92) decaying into thorium (atomic number 90). The daughter of a daughter isotope is sometimes called a granddaughter isotope.

What are daughter isotopes?

An isotope produced by the radioactive decay of the nuclei of another isotope (the parent isotope). For example, lead-206 is a daughter isotope of uranium-238, which has a half-life of 4.5 billion years.

Is U 239 A stable isotope?

Twenty plutonium radioisotopes have been characterized. The most stable are plutonium-244 with a half-life of 80.8 million years, plutonium-242 with a half-life of 373,300 years, and plutonium-239 with a half-life of 24,110 years. All of the remaining radioactive isotopes have half-lives that are less than 7,000 years.

What does U 238 decay into?

The half-life of uranium-238 is 4.5 billion years. It decays into radium-226, which in turn decays into radon-222. Radon-222 becomes polonium-210, which finally decays into a stable nuclide, lead.

Is lead a parent isotope?

Another important atomic clock used for dating purposes is based on the radioactive decay of the isotope carbon-14, which has a half-life of 5,730 years….RADIOMETRIC TIME SCALE.

Parent Isotope Stable Daughter Product Currently Accepted Half-Life Values
Thorium-232 Lead-208 14.0 billion years
Rubidium-87 Strontium-87 48.8 billion years

Is carbon 14 a parent isotope?

Like other unstable isotopes, carbon-14 breaks down, or decays. The original atoms are called the parent isotopes. For carbon-14 decay, each carbon-14 atom loses an beta particle.

Are daughter isotopes radioactive?

In 1896 Henri Becquerel and Marie Curie discovered that certain isotopes undergo spontaneous radioactive decay, transforming into new isotopes. Atoms of a parent radioactive isotope randomly decay into a daughter isotope. Over time the number of parent atoms decreases and the number of daughter atoms increases.

Is uranium 235 man made?

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. Uranium-235 is the only naturally occurring fissile isotope, which makes it widely used in nuclear power plants and nuclear weapons.

Which lead isotope is most common?

Lead has of four naturally occurring stable isotopes, 204Pb (1.4 %), 206Pb (24.1 %), 207Pb (22.1 %), and 208Pb (52.10 %).
