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.

Where did most of the alpha particles fired at the foil go in the gold foil experiment?
Most of them went right through.
What would happen if a proton was added to a aluminum atom?
If a proton were added to an atom of aluminum, the atom would become a silicon ion with a single positive charge.
The energy of the electrons passing along the electron transport chain is used to make what?
ATP molecules
What size particles are most dangerous to breath?
First of all this a bioscience question and not a particle physics question. Particle physics deals with the study of the properties of various subatomic particles. These particles cannot be seen by your eyes or a microscope. You would need a electron microscope or a more powerful instrument to see and study a particular particle. So please ask your question in the biology category.
What is the main purpose of a particle accelerator?
The main purpose of a particle accelerator is to generate synchrotron radiation or to smash atomic nuclei together or into a target to see what is produced from the energy of the impact. The results then inform which theoretical physical models are incorrect and occasionally which models have a valid experimental basis.
How may neutrons in Aluminium?
Aluminium has roughly a couple dozen isotopes; but the only one both stable and naturally occurring has 14 neutrons (mass number of 27).
How many electron shells does phosphours have?
Phosphorus in is 3rd period. So it has 3 electron shells.
Why do you have electrons in your body?
Your body is made of molecules which are made of atoms. All atoms have electrons.
What are quarks and its types?
a quark is a fundamental constituent of matter, the types are: up, down, top, bottom, strange and charm
How many electrons does Pb-82 have?
Atomic number of lead (Pb) is 82. So there are 82 protons and 82 electrons
What is number neutron in a phosphorus atom?
16 neutrons in the most stable isotope of phosphorus (15P31).
How are protons and neutron attract to the nucleus even if the have not the same charge?
They are attracted to each other due to the strong nuclear force, which is far stronger than the electro-magnetic force.
Who determined the charge on a single electron?
the charge of either a single proton, or the absolute charge of a single electron is approximately 1.602176487(40)×10−19 coulombs .The magnitude of the elementary charge was first measured in Robert A. Millikan's noted oil drop experiment in 1909
Gluons are bosons which mediate the force binding quarks to one another within a hadron (a particle made of quarks, such as a proton or neutron). No one person can take credit for first developing this theory, as quantum mechanics and the Standard Model are still developing. As these paradigms continued to develop in the 1960s and 1970s, the gluon hypothesis was found to explain a lot of observations that were easily explained with gluons but difficult to explain in other ways.
How many electrons shells would you expect to find in sulphur atom?
Sulfur contains atoms in three energy shells.
protons are very very tiny but compared to electrons they are big
What does the alleged discovery of the higgs boson particle mean when applied to string theory?
It doesn't mean much. The Higgs Boson is only necessary for the Standard Model to be correct; the Standard Model excludes gravity, and String Theory is a theory of quantum gravity. The two are separate from one another.
How are electrons related to electricity?
because electrons are the only particles that can move in an atom. so when current flows through a circuit it is really electrons moving
How do light and speed both appear as result from distance divided by time?
Probably that refers to the SPEED of light; and perhaps the speed of something else. Or speeds in general. A speed can be defined as a distance divide by a time, i.e., how much something moves in a second, or in a minute, for example.
What three subatomic particles are found in the nucleus?
The nucleus of an atom contains only protons and neutrons. Electrons orbit the nucleus.
What is a charge and how it differs from electrons protons or neutrons?
A charge is a property of matter that exerts a force on other charged particles. Electrons and protons have electric charges, with electrons having a negative charge and protons having a positive charge. Neutrons do not have an electric charge and are electrically neutral.
