The meaning of ATOMIC NUMBER is an experimentally determined number characteristic of a chemical element that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines t
atomic number, the number of achemical elementin the periodic system and on theperiodic tablethat equals the number of protons in the nucleus of the atom. The elements are arranged on the table in order of increasing number of protons in the nucleus. Accordingly, the number ofprotons, which...
Synchrotron-based X-ray spectroscopy is a powerful tool to study element-specific magnetism. Here, X-ray detected paramagnetic resonance on molecular quantum bit candidates is demonstrated, paving the way toward the element-specific detection of coherently excited spin superposition states. Andrin Doll ...
