No, there is no evidence to suggest that electrons are composed of precisely 100 particles. Electrons are elementary particles, which means they are considered fundamental and indivisible according to our current understanding of particle physics. According to the standard model of particle physics, electrons are point-like particles with no internal structure. They are classified as leptons and are not composed of any smaller constituents.
The idea that electrons are made up of 100 particles is not supported by scientific evidence or any established theories. It is important to differentiate between scientific knowledge based on empirical evidence and speculative ideas or misconceptions. Our current understanding of electrons is based on extensive experimental observations and theoretical models, which have not indicated any substructure within electrons.
