Scientists use the periodic table to quickly refer to information about an element, like atomic mass and chemical symbol. The periodic table’s arrangement also allows scientists to discern trends in ...

This Q-value calculation programme allows you to calculate reaction Q-values and threshold energies and decay Q values based on the 1995 Update to the Atomic Mass Evaluation and to retrieve other ...

The term ‘weighted mean mass’ takes into account the different contribution of each isotope to the overall mass. Relative atomic mass is not the same as mass number. Mass numbers close mass ...

was less than the atomic mass (average mass of the atom). For example, a helium atom has an atomic mass of 4, but an atomic number (or positive charge) of 2. Since electrons have almost no mass ...

Fission splits a heavy element (with a high atomic mass number) into fragments; while fusion joins two light elements (with a low atomic mass number), forming a heavier element. In both cases, energy ...

The market for Centrus Energy (NYSE: LEU) has reached a critical mass, and an atomic short-squeeze is on. The market has already risen more than 50% this year and could increase by another 25% to ...

A research team from Seoul National University College of Engineering has developed a technology to observe atomic structural changes of nanoparticles in three dimensions. Their study, which resolves ...

Chlorine naturally exists as two isotopes, \(_{17}^{35}\textrm{Cl}\) (chlorine-35) and \(_{17}^{37}\textrm{Cl}\) (chlorine-37). The abundance of chlorine-35 is 75% ...
