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.

The concept of baryons as a group of subatomic particles was developed by Murray Gell-Mann and Kazuhiko Nishijima in the 1950s. They observed and classified various particles based on their properties such as charge, strangeness, and isospin.

It is not letting me put the link in as normal, so I put the "dots" in.
Remember that momentum is conserved. Since initial momentum is zero (since it is at rest) the net momentum of the two particles must cancel each other to equal zero. They are traveling in opposite directions. Let the rest mass of one particle equal m1, then the rest mass of the other particle is (3.34 x 10^-27 kg) - (m1). Plug those into the relatavistic mass equations, and set the magnitudes of momentums equal. Then you can solve for m1.
How many protons neutrons and electrons are in k39?
In potassium-39 (K-39), there are 19 protons (since it's the element potassium), 20 neutrons (subtracting the element's atomic number from its atomic mass), and 19 electrons (since atoms are electrically neutral).
The rest energy of a pion is 140 MeV what is the kinetic energy when it moves at 0.80c?
total energy
E=gamma*m*c^2
where gamma = 1/sqrt(1-v^2/c^2)
K=E - mc^2 = (gamma-1)*(Rest Energy)
You know v, and can thus compute gamma, and you know the rest energy.
What is the force exerted only be by protons nearest?
The force exerted only by protons nearest to each other is the electromagnetic force. This force is responsible for repelling or attracting protons based on their charges, with like charges repelling each other and opposite charges attracting each other.
What subatomic particles are in a nucleus of vanadium?
A nucleus of vanadium contains protons and neutrons. Vanadium typically has 23 protons and 28 neutrons in its nucleus, resulting in an atomic mass of approximately 51.
Where is the large hardon collide?
Assuming you mean the Large Hadron Collider - and lise in a circular tunnel beneath the Swiss/French border.
The transfer or sharing of valence electrons creates chemical?
bonds between atoms. These bonds determine the reactivity, stability, and physical properties of a substance. The most common types of chemical bonds are covalent and ionic bonds.
Does electrons move from one object to anther when rubbed together?
Yes, when two objects are rubbed together, electrons can transfer from one object to the other. This transfer of electrons leads to one object becoming positively charged (loses electrons) and the other becoming negatively charged (gains electrons).
What happens to the electrons when an object is magnetized?
When an object is magnetized, the alignment of the electrons within the atoms of the material becomes coordinated, creating a magnetic field. This alignment allows the material to exhibit magnetic properties such as attracting or repelling other objects.
When an atom loses an electron it loses a?
Removal of an electron from an atom leaves a positively charged ion.
What is the antiparticle of a positron?
The antiparticle of a positron is an electron. Both the positron and electron have the same mass but opposite charge, with the positron having a positive charge and the electron having a negative charge.
Electrons are subatomic particles that are found within atoms, specifically in the electron cloud surrounding the nucleus. They are negatively charged and play a key role in chemical reactions and electricity. Electrons can also be found in free form in certain situations, such as in cathode ray tubes.
A Z-boson is an elementary particle that mediates the weak nuclear force. It is electrically neutral and is involved in processes such as neutrino interactions and particle decays. The Z-boson has a mass of about 91 GeV/c².
The Z boson is an elementary particle that mediates the weak force, one of the fundamental forces of nature. It is electrically neutral and plays a crucial role in processes such as nuclear beta decay and neutrino interactions. The discovery of the Z boson in 1983 provided strong evidence for the unification of the weak electromagnetic forces.
It would still be called carbon. THIS ACTUALLY EXISTS! The number of protons determines an element. Atoms with the same number of protons but different numbers of neutrons are said to be different ISOTOPES of an element. For example, the most common isotope of carbon is called carbon-12; since carbon has 6 protons, it means that the remaining 6 particles are neutrons. However, carbon-13 (6 protons, 7 neutrons) and carbon-14 (6 protons, 8 neutrons) also exist in nature.
What is the anti-particle of an electron?
That is called an anti-electron, also known as a positron.

That is called an anti-electron, also known as a positron.
An antibottom quark (or b-bar quark) is the antiparticle of a bottom quark. It has the same mass as a bottom quark but opposite electric charge and other quantum numbers. When a bottom quark meets an antibottom quark, they can annihilate each other and produce energy.
An anti-beauty quark, also known as a bottom antiquark, is the antiparticle counterpart of the beauty quark. It is a fundamental particle that has the opposite electric charge and other quantum numbers compared to the beauty quark. When a beauty quark and an anti-beauty quark pair up, they annihilate each other, releasing energy in the form of other particles.
An antiboson is the antiparticle of a boson, which is a type of subatomic particle that follows Bose-Einstein statistics. When an antiboson interacts with a boson, they can annihilate one another, releasing energy in the process.
An anti-charm quark is the antiparticle of the charm quark. Charm quarks are a type of elementary particle that is a building block of matter, as described in the Standard Model of particle physics. Anti-charm quarks have an electric charge of +2/3 and are involved in various particle interactions.
An anti-down quark is the antimatter counterpart of a down quark, one of the elementary particles that make up protons and neutrons in the atomic nucleus. It has opposite electric charge to a down quark and can combine with other quarks to form antimatter particles.
An antielectron, also known as a positron, is the antimatter counterpart of an electron. It has the same mass as an electron but carries a positive charge instead of a negative charge. When an antielectron and an electron meet, they annihilate each other, releasing energy in the form of photons.
What equals neutrons with protons?
In a neutral atom, the number of neutrons is usually approximately equal to the number of protons to maintain electrical neutrality. This balance ensures that the positive charge of the protons is counteracted by the negative charge of the electrons, leading to a stable atom.
Which statement about subatomic particles is not true?
Subatomic particles are the same size as basketballs.
