Using x-ray tubes, determined the charges on the nuclei of most atoms. He wrote"The atomic number of an element is equal to the number of protons in the nucleus".This work was used to reorganize the periodic table based upon atomic number i...
The atomic mass and the name of the element are shown below the symbol. The color indicates the physical state of the element at 25℃. The periodic table contains a wealth of chemistry information if you know how to read it. The...

The overall apparatus thus includes an electrical circuit in which a water capacitor having a known dielectric property is an element. The fuel gases are obtained from the water by the disassociation of the water molecule. The water molecules are split into component atomic elements (hydrogen and ...
An inventive compound of Formula (I) is optionally isotopically-labeled with an atom of the same element having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of other isotopes that are optionally present in the compounds provided he...

Moreover, the coordination effect of cerium element was expected to enhance the interfacial bonding strength of titanium and PEEK, and improve the mechanical properties of CF/PEEK-Ti composites. Applying the cerium coordination effect to improve metal-resin interface bonding also provides new insights ...
