atomic weight

"Borophene is a very interesting material, as it resembles carbon very closely including its atomic weight and electron structure but with more remarkable properties. Researchers are only starting to explore its applications," Pan said.

Because lithium has a small atomic weight and radius, the batteries have a high voltage and charge storage per unit mass and unit volume.

Each water molecule that is part of the cycle has a certain isotopic 'fingerprint,' or composition, which reflects small variations in the atomic weight of the oxygen and hydrogen atoms that comprise the molecule.

Rare earths refineries must contend with 17 metals, depending on a deposit's geology, each of which are nearly the same size and atomic weight, making separation complex.

In my chemistry class, we were told to memorize the periodic table and its atomic weights, and were graded accordingly.
