Sentence examples for decay of heavy elements from inspiring English sources

Helium on Earth comes from the alpha decay of heavy elements such as uranium and thorium found in the Earth's crust, and tends to accumulate in natural gas deposits.

Most of the helium in the universe was formed during Big Bang nucleosynthesis, but the amount of helium is steadily increasing due to the fusion of hydrogen in stellar nucleosynthesis (and, to a very slight degree, the alpha decay of heavy elements).

The age is then confirmed by measuring levels of strontium, which slowly accumulates from the decay of heavier elements.

Elements such as lead formed largely through the radioactive decay of heavier elements.

Any astatine that was present at the Earth's formation has long since decayed, and extant astatine has formed through the decay of heavier elements.

Several radioactive isotopes have been synthesized in the laboratory, either by fusing two atoms or by observing the decay of heavier elements.

The more neutron-rich darmstadtium isotopes are the most stable and are thus more promising for chemical studies; however, they can only be produced indirectly from the alpha decay of heavier elements, and indirect synthesis methods are not favourable for chemical studies.

Theorists have derived models to explain how unstable heavy nuclei are formed in violent stellar explosions, and then decay into the range of heavy elements that are found in the Universe today.

Several radioactive isotopes have been synthesized in the laboratory, either by fusion of the nuclei of lighter elements or as intermediate decay products of heavier elements.

And it is the lifetimes and decays of exotic nuclei in the uncharted territory near this drip line that will provide the key to understanding the formation of heavy elements in type II supernovae.
