The number of electrons in one mole of H2 molecule was found to be. 6.023x10^23
what are electrons ?
The electron is a subatomic particle with an initial electric charge of -1. Electrons are the first generation of the lepton particle family and are often regarded as elementary particles due to the lack of known components or substructure. The mass of an electron is roughly 1/1836 that of a proton. The electron's quantum mechanical characteristics include a half-integer intrinsic angular momentum (spin) given in units of the decreased Planck constant, Because electrons are fermions, they cannot inhabit the same quantum state, according to the Pauli exclusion principle. Electrons, like other elementary particles, have both particle and wave properties: they may collide with other particles and be diffracted like light.
Because electrons have a smaller mass and hence a longer de Broglie wavelength for a given energy, their wave characteristics are simpler to examine with experiments than those of other particles such as neutrons and protons.
