Just what IS an electron, exactly?
>>16792948My boogers.
>>16792948An electrically charged particle of mass 9.1 * 10^-31 kg and charge -1.6 * 10^-19 C
>>16792948
A quantized vibration in the electron field.
Just a particle which rotates around nucleus or whose probability of finding is max at certain regions around nucleus if you want to be pedantic. There's nothing inherently negative about it, it's our convention.
