Answer:Electrons exhibit interference or diffraction due to scattering objects or apertures around the same size as their de Broglie wavelength. Electrons exhibit a discrete charge. Electrons exhibit a discrete mass. Electrons may tunnel through barriers of nanometer or below thickness
Explanation:
Electrons behave both as matter an waves in accordance with De Broglie principle of wave particle duality hence they possess an associated wavelength and as such undergo diffraction and interference.
Electrons have a known magnitude of mass and charge.
Many studies have also shown that electrons can tunnel through barriers of 1nm thickness or less.
