Since the charge of the proton is a positive one, the number of protons vs. electrons in an atom is important in determining the charge of the atom. There is one atom that has only a single proton and no neutrons: hydrogen. As a neutron has no actual electrical charge, the only charge...
3.1 Isotopic Classification of the Elements An element is specified by the number of protons in its nucleus. This equals the atomic number of the respective element, and thus determines its place within the periodic table of the elements. The atomic number is given as a subscript preced- ing ...
A new gas inlet port combined with a novel ionization scheme have been developed and coupled to a high-resolution time-of-flight mass spectrometer (TOF MS) for the detection and measurement of atmospheric volatile (VOCs) and intermediate volatility organ
