The Standard Model.The Standard model is the ruling model that describes the world of the subatomic particles and interactions.LEPTONSQUARKSMatter- particles:
all common particlesElectron
Charge: -1
Responsible for electricity and chemical reactions.Electron-neutrino
Charge: none.
Also possibly no mass.
Move by billions per second through our body.Quark-Up
Charge: +2/3.
Protons contain two, neutrons one.Quark-Down
Charge: -1/3.
Protons contain one, neutrons two.These particles existed immediately after the Big Bang.
Now they are found by nature only in cosmic radiation.Muon
A more heavy variant of the electron.
Exists only one two millionth part of a second.Muon-neutrino
Comes into existence together with muons when particles fall apart.Quark-Charm
More heavy relation of the up-quark.Quark-Strange
More heavy relation of the down-quark.Tau
More heavy than Muon.
Very unstable.Tau-neutrino
Not yet discovered. The existence is assumed.Quark-Top
More heavy than Charm.Quark-Bottom
More heavy than Strange.
Force- particles:
Bearers of the four fundamental interactions of nature.Gluons
Bearers of thestrong nuclear force of quarks.Photons
Light particles.
Bearers of theelectromagnetic force.Intermediate vector bosons
W and Z particles.
Bearers of the weak nuclear forces.Gravitons
Bearers of thegravitational forces.
Hypothetical, Gravitons are not yet discovered.After: Natuur en Techniek 9, 1997.The release of nuclear energy during nuclear reactions is a result of the strong nuclear force.Electricity, magnetism and chemistry are results of the electro-magnetic force.Some forms of radioactivity are a result of the weak nuclear force.Our experience of 'weight' is a result of the gravitational force.

When an unstable nucleus produces an beta particle by how many units does the atomic number of the nucleus change?
The atomic number decreases by one for each beta particle
When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
How many kinds of fundamental particle have been discovered?
The fundamental paticles are Quarks , they are of 6 types.
What is a postively charged sub- atomic particle is called what?
There are many, but the most well known, and the one you are probably looking for, is the proton.
How many protons are in an alpha particle?
The alpha particle does not have any electrons. This particle is ejected from the nucleus of an atom in what is called alpha decay, and it appears as a pair of protons and a pair of neutrons fused together. The alpha particle is a helium-4 nucleus, and soon after it appears, it will collect a pair of electrons from its environment. But as it appears in the radioactive decay process, it doesn't have any electrons.

How many different elements scientists have discovered and studied?
What is a positive atomic partical
What are two types of physics?
Molecular, atomic, particle, and astro are just a few of the many different areas of physics.
What was discovered recently DNA pulsars quasars atomic power or radio waves?
None of them. They were all discovered a good many years ago.

How many moons go around Saturn?
Saturn has about 61 moons discovered to date, but there will probably more to be discovered
The atomic number is the number of what in an element?
An element's atomic number is a count of how many protons are normally part of the element's nucleus. Since protons are normally the only particle in the nucleus with a charge (+), the atomic number also represents the charge of the nucleus.
How many subatomic particles have been discovered to date?
more than 400
How many protons are in an alpha particle?
The alpha particle does not have any electrons. This particle is ejected from the nucleus of an atom in what is called alpha decay, and it appears as a pair of protons and a pair of neutrons fused together. The alpha particle is a helium-4 nucleus, and soon after it appears, it will collect a pair of electrons from its environment. But as it appears in the radioactive decay process, it doesn't have any electrons.
When an alpha particle is emitted the atomic increases by what?
The emission of an alpha particle (which is a Helium nucleus) from a radioactive nuclide would decrease its atomic number (z) by two, and its mass number by 4. So for example, Plutonium-239 (z=94) would emit the alpha particle and jump back down the table to Uranium-235 (z=92). It is possible to go up the table (increase atomic number) through certain beta decays.
