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.

How can a particle have a spin of 0.5?
Due to quantum-mechanical laws, the spins of particles have to be some integer multiple of a base value. This base value is 1/2, in the selected units, which relate to the reduced Plank's constant. Using different units, it might be multiples of something else. For example, using Plank's constant (instead of the reduced constant), it would be multiples of 1/(4 x pi). Special units can also be made up for particle spin, to make the spin a multiple of 1, or in fact of any other number you choose.
What happens in the number of electrons in the second shell?
Second shell has a maximum of 8 electrons.
Are the rest mass of the positron and the electron exactly equal?
Yes; they simply have opposite charges.
What electrical charge do protons neutrons and electrons have?
Protons have a positive charge, neutrons have no charge, and electrons have negative charge.
Neutrons do not carry an electrical charge:)
A proton has a positive charge. Remember, NEUTRon = NEUTRal. Proton = Positive. The electrical charge of a proton is 1.6x10^-19 which is equal and opposite to the electrical charge of an electron which is -1.6x10^-19.
What 2 subatomic particles can you determine from the atomic number?
Atomic number is same as the number of protons and number of electrons.
Did democritus discover electrons?
no, he could have never even imagined them. also he didn't discover a thing, he like all other philosophers of his time just made wild untestable guesses about how nature worked.
Why is harder for group 7 atoms to gain an electron?
Group 7 atoms, also known as the halogens, have a full outer electron shell and are one electron short of having a full shell. Due to their high electronegativity and small atomic radius, they strongly attract electrons in order to achieve a stable electron configuration, making it harder for them to gain an additional electron.
How many positive subatomic particles does cadmium have?
Cadmium has 48 positive subatomic particles, which corresponds to its atomic number. This number indicates that cadmium has 48 protons in its nucleus. Since a neutral atom also has an equal number of electrons, cadmium has 48 electrons as well.
What is the main goal of density and atomic spacing experiment?
The main goal of a density and atomic spacing experiment is to determine the relationship between the mass and volume of a substance, allowing for the calculation of its density. By examining atomic spacing, the experiment aims to understand how the arrangement of atoms within a material influences its density and other physical properties. This information is fundamental in materials science, enabling the development and optimization of new materials for various applications.
Is the Large Hadron Collider dangerous?
I assume you are asking about the myth that somehow the LHC will create a singularity (black hole) and ,for lack of a better word, absorb the solar system. In which case the answer is no the LHC is perfectly safe,
However there are always risks with any high energy particle experiments, radiation and high magnetic fields are of course a by product of the project, though there is no need to worry about any of those phenomena as they are safely contained and shielded
Why does your 1995 gmc vandura 2500 stall when the accelerator is pressed?
fuel filter has to be changed every 8000 miles or sooner if it plugsup sooner
Who is the founder of Antimatter?
The founder of antimatter is considered to be the physicist called Paul Dirac in 1928-1930. He created a mathematical equation which predicted the existence of antiworld made out of antimatter.
By recreating Big Bang conditions, scientists at CERN trie to answer following questions:
- Why is there no-more antimatter left, although both, matter and antimatter were resulting from the Big Bang in equal parts and thus, should've annihilate themselves?
- Why do particles have mass? What is mass? Is the origin of mass the Higgs-boson?
- Does dark matter exist? What is dark matter?
- Do extra dimensions exist?
How may electrons equal one proton?
In charge, spin, and strangeness; they are exactly equal.
In mass, it would take about 1836 electrons to equal a proton.
Why are protons and neutrons used in the subatomic particle?
Protons and neutrons provide the mass of an atom. Each different kind of element has a unique number of protons. For example: all hydrogen atoms have one proton. However, not all hydrogen atoms have the same mass. Some hydrogen atoms have no neutrons, one neutron, or two neutrons. Atoms of the same element (one proton) but different numbers of neutrons (different masses) are called isotopes of that element. All elements have isotopes. Some isotopes of elements are radioactive and are useful in medicine and energy applications (nuclear, for instance).
The amount of planet matter equal to that of the astronaut would annihilate.
How do you go from a proton to the higgs boson?
since the proton-proton collision produce higgs bosons where was the higgs in the first place?
Dark matter is so named because it does not interact electromagnetically and thus isn't observed directly with visible light; yet possesses mass. Dark matter is significant to cosmology due to unsolved questions arising from observations about the apparent mass of the universe. Several candidates have been proposed for the makeup of dark matter including near-massless subatomnic particles such as neutrinos.
The term 'black material' by contrast would imply something far more mundane, the simple property of matter wherein its surface would tend to absorb a significant fraction of incident light and thus have a black appearance to an observer.
How is background radiation caused from rocks soil and cosmic rays?
Rocks and soil contain small amounts of naturally occurring radioisotopes as well as various amounts of fallout from atmospheric nuclear testing and the Chernobyl reactor accident. Cosmic rays are in large part nuclei ejected with high velocity by ancient supernovas.
Can unified field theory prove the ghost?
Unified Field Theory is science. By the very definition of science, ghosts are nonscientific because they have not been proven to exist. Further, Unified Field Theory describes nothingexcept for the unification of the four fundamental forces.
