We now know there are are six quarks (or called flavours of quarks), which are grouped into 3 pairs (or generations); up & down, charmed & strange and top and bottom. It is these fundamental particles which form neutrons, protons etc, which are collectively known as hadrons, (it is mainly the up and down which form the world around us). The quarks are peculiar as they posses a charge which is a fraction of that for the electron. There are two types of hadron, the Baryon which is a system of three quarks (e.g. the proton) or Mesons, a two quark system containing a quark - antiquark pair (e.g. the pion or pi-meson).
Leptons are particles such as muons and electrons, there are 6 leptons in total, each with their anti-lepton counterpart. For the electron, muon and taon (which are referred to as different flavours of the lepton) there is a corresponding neutrino (a lepton) associated with it.
Difference between the two: Leptons do not participate in the strong interaction and are generally not seen within the nucleus.
Bosons are often force carrier particles (these are typically referred to as gauge bosons). In the prevailing Standard Model of physics, the photon is one of four gauge bosons in the electroweak interaction; the other three are denoted W+, W− and Z0 and are responsible for the weak interaction.

What is all the matter in the universe made of?
quarks and leptons, held together by gluons, W+ bosons, W- bosons, photons, and gravitons
Are electrons examples of hadrons?
The answer is no: electrons are fermions while mesons are bosons.
Type of particle thought to compose protons and neutrons?
There are two types of subatomic particles hypothesized to comprise protons and neutrons. Elementary particles having mass by the types of quarks, leptons and bosons are the first. The second are composite particles, which include baryons, mesons, and leptons.
What are the parts of the atom besides the neutron?
The nucleus which includes the protons and neutrons, and the electron cloud which contains the electrons. If you want to get into true quantum mechanics, then there are the quarks, the leptons, the bosons, gluons, etc.
What are the 12 particles of matter?
The Standard Theory of quantum mechanics outlines our current understanding of the very, VERY small. It describes 3 main groups: 6 fermions and 6 leptons, which have mass and make up matter, and 4 bosons, which carry forces between particles. The 6 fermions, better known as "quarks", are the up, down, strange, charm, top, and bottom quarks. The 6 leptons are the electron, muon, and tauon, plus a specific type of neutrino for each. All 12 of these particles also have an antiparticle, which aside from the electron (whose antiparticle is the positron) are creatively labeled by putting an "anti-" before any of the above particles. Additionally, the 4 bosons, which carry forces between charged particles are the photon, which mediates the electromagnetic forces and which we observe as light; the gluon, which mediates the strong force between quarks (and holds nuclei together); and the W and Z bosons, which mediate the weak force.
What is a subatomic particle known as?
They are leptons, bosons, hadrons, fermions etc.
What is all of the matter in the universe made of?
quarks and leptons, held together by gluons, W+ bosons, W- bosons, photons, and gravitons
What is all the matter in the universe made of?

All matter is made up of what?
quarks and leptons, held together by gluons, W+ bosons, W- bosons, gravitons, and photons
Are electrons examples of hadrons?
The answer is no: electrons are fermions while mesons are bosons.
All elements are composed of extremely small particals called?
...elementary particles... quarks, leptons, and gauge bosons electrons protons and neutrons
What is the standard model of particle physics?
Six quarks, six leptons, 2 weak gauge bosons, the photon, 8 gluons, the Higgs, and the hypothetical graviton
What particles are found in the nucleus of an atom and what charge do they have?
Without speaking about quarks, leptons and bosons (which are more complicated), the nucleus has neutrons (no charge) and protons (positive charge).
What particles or structure would not contain any quarks?
Any particle that is not a hadron does not contain quarks. Fundamental bosons and leptons are the only category of particles that do not contain quarks.
What arent quarks leptons and bosons studied?
They are wideley studied around the world. Look at the particle collider, and all the Neutrino observatories. The fact we have an understanding of why they exsist and what they contribute towards the atom is a very profound and is proof they are widely studied everyday. Neutrinos are Leptons by the way.
Type of particle thought to compose protons and neutrons?
There are two types of subatomic particles hypothesized to comprise protons and neutrons. Elementary particles having mass by the types of quarks, leptons and bosons are the first. The second are composite particles, which include baryons, mesons, and leptons.
What are cement brick steel and glass?
Mostly quarks, some leptons. If you ask an electrodynamical purist they'll also tell you that they are made out of gauge bosons, but how long is the nose of the emperor of china?
