WebAug 6, 2024 · Which is the first noble gas on the periodic table? Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. The chemical symbol for Helium is He. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. WebDec 6, 2024 · The reactant gas partial pressure is shown as an averaged value throughout the gas channel, taking into account the pressure decrease due to the electrochemical reactions. It is seen that the limiting current densities were proportional to the reactant gas partial pressure.
