Lepton
A centimeter is smaller than a meter
450 is smaller than 900.
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
The lepton number of an electron is important in particle physics because it helps to determine the conservation of leptons in interactions. Lepton number is a fundamental property that must be conserved in particle interactions, and it helps to understand the behavior of particles and their interactions in the subatomic world.
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.
The principle of lepton number conservation states that the total number of leptons (such as electrons and neutrinos) must remain constant before and after a particle interaction. This principle helps to predict and understand the outcomes of particle interactions by ensuring that the total lepton number is conserved throughout the process.
The conservation of lepton number in particle physics is important because it helps to explain why certain particles exist and why certain interactions occur. Lepton number conservation ensures that the total number of leptons (such as electrons and neutrinos) remains constant in a given reaction, which helps to maintain the stability and balance of fundamental particles in the universe. Violations of lepton number conservation could lead to new discoveries and insights into the nature of particle interactions.
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.
