Bein fermions, na twa electrons can occupy the same quantum state, in accordance wi the [[Pauli exclusion principle]].<ref name="curtis74"/> Electrons an aa hae properties o [[Wave–pairticle duality|baith pairticles an waves]], an sae can collide wi ither pairticles an can be [[diffraction|diffractit]] lik licht. Experiments wi electrons best demonstrate this duality acause electrons hae a tiny mass.
