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.
An atom is larger than a neutron; a neutron is a part of any atom except a hydrogen atom.
The valence electrons occur in what part of the atom?
its the greatest part of an atom
Neutron
The nucleus of the atom is stationary.
Because the electron is a lepton, and is not made of quarks.
That should be the lepton. The electronic lepton (e-) to be accurate. More information: http://en.wikipedia.org/wiki/Lepton
The smallest particle that retains the properties of an element is an atom. Quarks and leptons are just a family of elementary particles and do not carry any properties of the element.
If the pure substance is not an element, the smallest part is a molecule (which is made of atoms) for instance, pure water is made of water molecules, which are made of 2 hydrogen atoms and 1 oxygen atom If the pure substance is an element, the smallest part is an atom. (which is made of Protons, Neutrons, and Electrons) Pure hydrogen is made of atoms. A stable hydrogen atom has 1 proton, 1 neutron, and 1 electron. Protons and Neutrons can be broken down further into Quarks, Leptons, and Bosons. The Electron is a type of Lepton.

Lepton wavelength and spin are not related. Leptons have a spin of 1/2 regardless of wavelength.
no an atom is a part of a molecule.
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).
Electrons, down quarks, strange quarks, bottom quarks, muon lepton, and tau lepton all have negative charge. Also, the boson can be negative.
Lepton
The smallest part of an element that still retains its properties is an atom.
