Electrons have mass, electrical charge, and a magnetic moment , and all of those things are physical properties. So yes, electrons are material. > > Last year, a trio of physicists in Italy deduced that electrons would > last 5 quitillion times the current age of the univeres I've heard some speculate that the proton might be unstable over huge time ranges like that, but not the electron. For a electron to decay it would have to change into a charged particle that was lighter than it was, but the electron (and its antimatter counterpart the positron) is the lightest known charged particle, so there is nothing for the electron to decay into. A Muon is very similar to the electron except that it's 207 times as massive, so in about a millionth of a second it decays into a electron and 2 neutrinos, but the electron is the end of the line, there is no place for the electron to go so it sticks around. The same is true of the neutrino, like the electron it's stable, fundamental and isn't made of anything.
