Isotope hydrology helps governments find and understand the source of their water supplies – so they can develop management ...

The chemical bonds and attractive forces of atoms with heavy stable isotopes are stronger than those in the more common, lighter isotopes of an element. As a result, the heavier isotopes react more ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei – the center part of atoms, which make up all matter – were more ...

Explain that the pennies, dice, and sugar cubes represent atoms of different radioactive isotopes. The boxes symbolize rocks containing those isotopes. Each team's mission is to determine the half ...

This isotope of hydrogen is called deuterium, and heavy water's more scientific name is deuterium oxide, abbreviated as D 2 0. Nuclear power plants harness the energy of countless atoms of uranium ...

For the first time, scientists have characterized a promethium coordination complex, advancing the understanding of ...

Ensure students have an understanding of how mass and atomic numbers can explain the number of protons, neutrons and electrons in atoms. Explain with examples that isotopes have the same number of ...

Lithium-6 is a crucial material for nuclear fusion reactors, but isolating it is challenging – now researchers have found a ...

However, the scientists were taken by surprise when oxygen-28 quickly decayed into another isotope, contradicting one of ...

1. Convert kilograms/second to grams per second. 1 kg = 1000 grams. If the mass flowrate is 0.25 kilograms/second, convert this to 250 grams/second. 2. Convert grams to moles, using the molar mass of ...
