Lepton
450 is smaller than 900.
A centimeter is smaller than a meter
A probability can be no larger than 1 and no smaller than 0.
Smaller.
An electron is a Lepton - it doesn't have any smaller parts.
The wavelength of a lepton is inversely proportional to its momentum, which is related to its energy and mass. The spin of a lepton is a fundamental property intrinsic to the particle itself, independent of its momentum or 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).
Lepton
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.
A newton is larger than a dyne and smaller than a kilogram-force.
Yes, there are smaller particles than protons, neutrons, and electrons. Quarks are even smaller particles that make up protons and neutrons. Additionally, there are particles such as neutrinos, gluons, and bosons that are smaller than protons, neutrons, and electrons.
it can get smaller than an atom
Ofcourse sea is smaller than an ocean
