Particle Physics

proton mass = 1.6726 × 10-27 kg

electron mass = 9.109 × 10-31 kg

neutron mass = 1.6749 x 10-27 kg

There are many subatomic partials but the three basic ones are: the electron, the neutron, and the proton. The electron has a negative (-) charge. the proton has a positive (+) charge. and, The neutron doesn't have a charge (but has more mass).

if you where talking about quarks, they are a bit more complex (and theoretical) and I don't rely know...

The neutron was discovered in 1932 by James Chadwick.

The atomic number of Mg (and not written as mg) is 12. So there are 12 protons and 12 electrons

Note:

Mg is the symbol for the element magnesium

mg generally stands for milli grams

Three reasons:

1) Its large mass requires a LOT of kinetic energy in any collision to end up with enough energy to even possibly result in a Higgs Boson being created. That's why no particle accelerator prior to FermiLab or CERN had anywhere near enough energy to even hope to make a Higgs.

2) The Higgs is a VERY unstable particle -- once created, it breaks down into other particles in a time on the order of 10^-22 seconds. No device can possibly detect a particle in existence for that length of time, so we are left with looking for the decay products of a Higgs.

3) A LOT of other particles have decay products that very closely resemble that of the Higgs, so we can never be 100% certain that "these decay products are from Higgs Bosons, while these are not." All we can do is make a LOT of collisions, record the decay products of all of them, and then ask the question, "What is the probability that NONE of these decay products are a Higgs?" The most recent data from CERN have led scientists to state that the odds that zero Higgs were created is 1000 to 1 -- pretty good odds. However, particle science protocol requires that this probability must be reduced to a million to one before stating, "The particle that we were looking for was definitely created during these experiments." That announcement will probably occur in the next year or so.

I believe there are 3 electrons

Definatly not! A Neutron is a kind of Baryon (a type of Hadron) made up of the subatomic particles: Up quark, Down quark and Electrons. Now a Neutrino is different, there are three different types. There are Electron Neutrinoes, Muon Neutrinoes, and Tau Neutrinoes. Neutrinos are a type of Lepton, for every Neutrino there is a equivalent non-neutrino. For example, There is an Electron and an Electron Neutrino. So to conclude Neutrino does not mean Neutron, instead it is describing a type of Lepton. This should answer the Question.

It a humorous name for a hoped-for scientific theory -- not yet developed -- out of which we could derive all four forces in our Universe. Another name is Grand Unification.

As an example of what unification means, Isaac Newton was able to unify the law of orbits of planets around our Sun with the law of falling bodies on the surface of our Earth -- either can be derived by Newton's Law of Gravity.

At present we have a law dealing with gravity -- general relativity -- and a law dealing with the other three forces -- the Standard Model -- but these two laws are completely incompatible with each other. A single law from which we could derive both of these other two laws has been called the "Theory of Everything." There is nothing religious about it whatsoever.

Yes, indeed there is. When I get up off the sofa and walk into the kitchen for a

glass of milk, I have accelerated at a higher rate than the acceleration of light,

since the speed of light is constant and it doesn't accelerate.

If, on the other hand, you're asking if any object has a speed higher than the speed of light, then the answer is a little more subtle. Relativity makes it clear that no object carrying information can travel faster than the speed of light. Until a few months ago, this "speed limit" seemed pretty safe.

Recent experiments at CERN suggest neutrinos going to Italy at a rate faster than the speed of light, but even the CERN experimenters admit they have probably made an error. It's just that nobody's been able to find the error yet.

Nothing, quarks are the sole matter of things, they are the base of things.

The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.

Argon is a non metal element. There are 18 electrons in a single atom.

When electrons are shared between atoms, it forms a covalent bond. In a covalent bond, atoms share electrons to achieve a stable electron configuration. This type of bond is common in nonmetallic elements.

Nickel is a chemical metal element. There are 28 electrons in a single atom.

A lithium ion (Li+) has one less electron than a neutral lithium atom. This means a lithium ion has 3 electrons.

Mist is composed of tiny liquid water droplets suspended in the air. These droplets are formed when water vapor in the air condenses into droplets due to cooling or mixing with cooler air. Mist is typically lighter than fog and can reduce visibility but is not as thick or as low to the ground as fog.

A particle with 47 protons and a +1 charge is a silver ion, specifically silver-47 or Ag+1.

An atom of antimony has 5 outer shell electrons. Antimony is in group 15 of the periodic table, so it has 5 valence electrons.

Iodine has 53 protons, while silver has 47 protons.

It does produce current, locally, but in atom electron oscillates and can be compared to frictionless pendulum. So the produced current nulls itself externally. At least most of it. some current is absorbed, as temperature generated noise.

They aren't 3 they are in fact 12 if you count anti matter as a separate particle from matter.

Electron, muon, tau, electron neutrino, muon neutrino and tau neutrino.

The same apply to anti matter positron, anti muon, anti tau, postrin neutrino, anti muon neutrino, and anti tau neutrino.

Yes, free electrons can collide with atoms. When a free electron collides with an atom, it can transfer energy to the atom, which may result in ionization or excitation of the atom. These collisions play a significant role in processes like electrical conduction and plasma interactions.

Which scientist DID NOT contribute in finding a subatomic particle?

AAristotle

BThompson

CRutherford

DChadwhick

Atoms were found to be divisible after all . But scientists discovered that the atoms were made of smller perticles , called subatomic particles.

Correct!
