Lepton
450 is smaller than 900.
A centimeter is smaller than a meter
Smaller.
A probability can be no larger than 1 and no smaller than 0.
An electron is a Lepton - it doesn't have any smaller parts.

muon
Lepton wavelength and spin are not related. Leptons have a spin of 1/2 regardless of wavelength.
There is currently no scientific evidence for any constituents of an electron. So, for now, the electron is a lepton (a lepton is any fundamental particle).

Leptons have mass.According to special relativity, no particle with mass can travel at or faster than the speed of light. It would take infinite energy to do so.
Lepton is the common name given to electron, positron, neutrino, antinuetrino, mu-meson [muon] etc. So an atom has these elementary particles within and come out in specific circumstances.
Smaller, Mars is about half the size of Earth
it can get smaller than an atom
It is smaller than a kilonewton.
