Matter is anything that occupies space and has mass.
and it is divided in to five states namely
so saying that TO WHICH STATE OF MATTER DOES ELECTRON OR OTHER FUNDA PARTICLES BELONG?
NOTE:- ELECTRONS HAVE MASS AND OCCUPIES SPACE NO MATTER HOW SMALL IT IS

i think electron is a constituent of matter than matter itself.to describe a state you must need an aggregate of constituent and it will their mutual spacing and interactions that will determine the state..
I agree with quarkine. But yes, the definition of matter you have given does seem incomplete. It's the same thing as asking what state of matter is one molecule of water? The question only has meaning when considering an aggregate of molecules and the conditions under which they exist.
That being said, one proton (or electron, etc) cannot be said to have a state of matter but perhaps an aggregate of protons can. Now, the conditions under which the aggregate of protons existed would have to be considered to even begin to propose an answer to this question.
