Particle Physics
Relatively recent experimental results have confirmed what philosophers throughout history had theorized all along; that all matter is made up of elementary particles. Those curious about this cutting-edge field of physics known as particle physics should post their questions here, including those about fundamental particles, fundamental forces, Grand Unified Theories, and the extraordinary devices that have been or need to be engineered to research them.

Which subatomic particles are located in the nucleus of a carbon atom?
Atomic nucleus contain neutrons and protons; and both contain quarks and gluons.
What happens to the stability of atom when they form covalent electrons?
The term 'covalent' is usually applied to a bond in the context of chemistry; electrons are the particles that participate in bonding. The act of bonding helps atoms achieve a stable configuration, one way of achieving this is by sharing its outer electrons in a bond. One might say the stability of an atom increases thereby.
How many electrons are there in Mg2?
Any atom of magnesium will have 12 protons.
Neutral atoms of Mg-24 will have 12 neutrons and 12 electrons. Mg-25 has 13 neutrons and Mg-26 has 14 neutrons. A magnesium ion will have either 10 or 11 electrons.
Why does the path of the beta particles bend more than the path of the alpha particles?
Beta particles (electrons) are less massive than alpha particles (Helium-4 nuclei), by a factor of approximately 8000.
How is the spin of an elementary particle measured?
Spin is either up or down and in positive half integer multiples of an angular momentum quantum constant:
h/(2∏), where h is Planck's constant.
What is beta radiation properties?
Beta particles or radiation is an electron emitted at high speed or energy from some types of unstable elements in a process known as beta-decay.
Beta radiation is not healthy for living things. It is usually stopped by a few millimeters of metal, wood, or plastic. Direct exposure to the skin can cause radiation burns.
Can you pay online by visa electron?
It depends on the website. Some websites only accept Visa or Mastercard credit cards while many others are happy to accept debit cards such as Electron, Solo and Maestro.
No, gamma rays are not neutrons. They are electromagnetic rays or electromagnetic energy.
As of October 30, 2009 particles are back in the Large Hadron Collider (LHC). To get periodic updates on the LHC in the form of videos go to http:/public.web.cern.ch/public
Is The neutron the most important part of the atom in forming compounds?
nope, electron. nothing in the nucleus participates in chemistry.
What is a generic name for the subatomic particles in the nucleus of an atom?
Nucleons, comprising protons and neutrons, are the generic name for the subatomic particles found in the nucleus of an atom.
What is the electron-pair geometry for SeOF2?
SeOF2 is known as Selenyl Difluoride. The Se atom has one pair of electrons, each F atom has three pairs, and the O has two pairs of electrons.
Does the string theory bridge the gap between Einstein's theory of relativity and quantum mechanics?
No, string theory is an attempt to bridge the gap between EVERYTHING, not just relativity and quantum, into one fundamental theory.
A mixture of down and up quarks and antiquarks. D-antiD, D-antiU, U-antiD, or U-antiU.
Which subatomic particles account for most of an atoms mass?
The up and down quark accounts for most of an atoms mass. Two up quarks and one down quark forms a proton, and one up quark and two down quarks forms a neutron. Protons and neutrons form the nuclei of atoms, and comprise most of their mass, along with the binding energy holding them all together.
It is mean as total colour that is red + green + blue = white (quantum number in physics) it is singlet. (Actually, since mesons have only two quark components, they're all quark-antiquark pairs and they're color + anticolor rather than red + green + blue.)
Why are gravitational electromagnetic and nuclear forces often called fundamental or basic forces?
Gravitational, electromagnetic, and the strong and weak nuclear forces are called the fundamental forces because, as far as we have been able to see, all phenomena in the universe can be explained as an expression of one or more of those forces. From a technical standpoint, these are the ONLY forces, but the word 'force' is commonly used when explaining mechanical processes. Therefore, the terms 'fundamental' and 'basic' can also serve to distinguish the use of the word 'force'. Forces like friction, air resistance, and general 'pushing' are all expressions of the electromagnetic force, so they aren't really additional forces. It would be nice if we had a different word for these forces and the 4 fundamental forces to keep things clear, but both uses lay equal claim to the word.
When scientists were studying this. They realized the Electromagnetic and the Weak Nuclear Force were very related, they combined this to form the Electroweak theory. So they suppose they were ALL at one time the same force called Supergravity.
Gravity- Force that pulls to the ground.
Electromagnetic - Combination of Electricity and Magnetics, reason your TV works.
Weak Nuclear Force - Makes Suns energy and Nuclear energy. Also responsible for holding quarks inside the protons and neutrons, Asymptotic Freedom.
Strong Nuclear Force - Holds Protons, Neutrons, and Electrons in the atom.
Why U 235 is fissioned by thermal neutron while U 238 by a fast neutron?
It's to do with the capture cross-section of the nucleus. It just happens that the U-235 nucleus has a much larger cross-section for neutron capture when the neutrons are slow, and that the subsequent nucleus is unstable and splits into two parts. With U-238, it does not undergo fission at all, it just absorbs the fast neutron and transmutes to Pu-239.
As to the fundamental reason for this, it is in the complex nuclear physics field of study
What could be a sentence for electron?
Atoms with larger atomic numbers have a larger electron cloud, or system of orbitals
What is the Higgs boson accelerator?
It isn't. The Large Hadron Collider is a proton-accelerator & collider designed to investigate the most fundamental sub-atomic particles and forces, and to try to prove or disprove the existence & properties of the hypothesised Higgs Boson, though to be responsible for mass.
It's true the World Wide Web was invented at CERN.
More precisely by Tim Berners-Lee 1989, Originally to create an information sharing system for scientists working at different universities and research institutes.
The WWW was later refined by Tim Berners-Lee and Robert Cailliau 1990.
Why are electrons affected by the addition of heat light or electricity?
Each of those has energy; so each of them MAY, under certain circumstances, knock an electron out of its orbit around the atom, or make it move around.
An antihydrogen is an atom of the antimatter equivalent of hydrogen, or the antimatter equivalent of hydrogen as a collective.
