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.

What is the Unified Field Theory?

The grand unified theory of matter and energy has been copyrighted, on 11/07/05 as U.S. copyright Txu1-266-788. It is available from Symmecon Grand Unified Theory Marketing Corporation, (NM, 04/02/07), at symmecon.com. The theory is presented in the book titled The Crystalon Door by Dale Clough, B. A.

Can traveling at the speed of light melt iron?

It isn't clear at all what you mean. In any case, it isn't possible to travel at the speed of light - except for specific particles, such as photons (pieces of light), which can ONLY travel at the speed of light.

What are 3 subatomic particles with their charge symbol function and where you find them in the atom?

The atomic nucleus contain protons (positive) and neutrons (neutral). Around the nucleus a cloud of electrons (negative) moves. The number of protons is equal to the atomic number and is the identity of an atom.

What is a proton-proton chain?

The proton-proton chain is the name given to one common fusion reaction occurring in stars by which hydrogen is converted to helium, along with the release of energy.

Are electrons in an atom related to protons?

Yes, electrons are negatively charged subatomic particles that are attracted to the positively charged protons in the nucleus of an atom. They are crucial for determining the chemical behavior of an element and are arranged in specific energy levels around the nucleus.

What element has as many electrons as it has neutrons?

There are particular isotopes that have similar number of electrons and neutrons. Some of these isotopes include hydrogen-2, helium-4, carbon-12 and nitrogen-14.

How do you figure out how many electrons are in a tungsten atom?

To find it you must go to the periodic table and read the two numbers one is the mass number (top one) the other is the atomic number(bottom) you need that one to find the number of electrons

How do install a tach on a 00 ford ranger 2.5l I have it hooked up to one coil but it has 2 randomly on a 4 cyl motor if that doesn't confuse everyone 8 spark plugs 4 cyl is the dumbed down version?

There are two coils on the 2.5 one fires on intake and one fires on exhaust stroke. the easy way to figure this out is look at the plug wires one set leads under the exhaust manifold thus the exhaust and the other leads to the passenger side of motor the intake. There is a plug on each of these and it really won't make much difference which plug you hook up to because they fire very close but I would hook it up to the intake. three wires the grey and light orange wire is the wire you should hook it up to.

What does an isotope release as a beta particle?

Usually when isotopes undergo beta decay they emit an electron, but some isotopes emit a positron instead. This depends on the relative number of neutrons to protons in the isotope which type of beta particle is emitted. An excess of neutrons leads to the emission of an electron, while an excess of protons leads to the emission of a positron.

How many neutrons does zine has?

Zinc ahas the following isotopes in nature each pof which has different number of neutrons.

zinc-64, 66, 67, 70. There are many synthetic unstable isotopes -

The atomic number of zinc is 30 so the most common isotope has zinc-64 has 64-30 neutrons = 34 in all

Which fundamental forces of nature is the weakest?

The gravity force is the weakest of the standard fundamental four forces of nature.

To demonstrate just how weak it is, we can easily overcome gravity with a simple electro-magnet and pick up nails against the force of gravity. Or, as you just sit there reading this, you are demonstrating how weak gravity is because you are not sinking into the fabric of the chair you're sitting on. Why? Because the electro-magnetic force surrounding the atoms of the chair and your rear are preventing the gravity from pulling you into the chair.

Why do biologists continue to use the light microscope since the invention of the electron microscope?

Biologists continue to use light microscopes because they are versatile, easy to use, and cost-effective for observing live samples. Light microscopes are better suited for visualizing large-scale structures and dynamic processes in living organisms. Electron microscopes are mainly used for high-resolution imaging of smaller structures at the subcellular level.

Where does the electron transport chain get its electrons from?

it gets electrons[2 eletrons from NADH and 2 electrons from FADH2] from NADH and FADH2....In case of NADH- it is directly from glycolysis but in case of FADH2-it is not directly attached to ETC but succinate is oxidised to fumarate realising FADH2

When did the Large Hadron Collider open?

The first beam was circulated on September 10, 2008.

The inaugural ceremony was on October 21, 2008.

The first particle collisions in all four detectors was on November 23, 2009.

How can neutrino oscillation explain the solar neutrino problem?

The solar neutrino problem relates to the discrepancy between the proportions of the different flavours of neutrinos emitted by the sun in the theoretical model as opposed to experimental measurements. Whilst the sun primarily emitts electron neutrinos, neutrino observatories such as SNO+ detected neutrinos in roughly equal proportions of the three flavours; furthermore the quantity of electron neutrinos detected was less than the theoretically predicted value. Both of these can be explained by neutrino oscillation - in which the neutrinos alter their mass to change their flavour (ie. an electron neutrinos gain mass to change to a muon neutrino). This would also explain the relative lack of electron neutrinos, thus solving the solar neutrino problem!

Free electrons are produced at the metallic electrode that?

Free electrons are produced at the metallic electrode that has atoms, that give up electrons, and become ions in solution.

How neutrons were discovered?

When Beryllium is bombarded with alpha particle some stream of particles are found to be coming out. First such an experiment was done by Bothe and Becker. But they mistook those particles coming out as intense gamma radiation as it was not deflected by magnetic or electric field. Later the same experiment was done by Fredrick Joliot and his wife Irene Joliot. They too lost the chance of finding that as neutron. Finally James Chadwick did the same experiment and found precisely the particles having almost equal mass as that of proton and not having any charge. He named that one as Neutron.

Are neutrinos mediated by electromagnetic interaction?

No, neutrinos are mediated by weak interactions, Photons are mediated by electromagnetic interactions.

How many electrons will a Cl-7 ion have?

Chlorine will not for Cl-7 ion. It will form Cl-1 ion, which has total of 18 electrons.
