Atomic mass dependence of the nuclear quantum effect in NH 4 + ( H 2 O ) NH4+(H2O)Kazuaki KuwahataMasanori Tachikawa
2. The Atomic Mass of an atom = number of Protons + Neutrons in the nucleus. 3. The number of Protons = Number of Electrons. 4. Electrons orbit the nucleus in shells. 5. Each shell can only carry a set number of electrons. Isotopes ? Atoms of the same element (same Z) but ...
The electrochemical quartz crystal microbalance (EQCM) is a technique that monitors the mass of the working electrode as a function of time: the test material is deposited on a thin quartz crystal wafer, the resonance frequency of which, under optimum conditions, is inversely proportional to...
