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 do you convert matter to antimatter?
You don't. You may have gotten the idea from the fact that we named both of them with 'matter' in the label. But they don't convert.
Which has the same number of which type of subatomic particle?
All elements have the same number of positively charged protons and negatively charged electrons to maintain electrical / charge neutrality
What factor usually determines whether a substance is a solid liquid gas or plasma?
The distance between particles
Where was the antimatter taken in angels and demons?
It was found on saint Peter's tomb deep inside Saint Peter's basilica by The Chamberlengo. He and Mr. Langdon then took it up in the Swiss Gaurd's helicopter, then the Camberlengo grabbed the only parachute and jumped out. Mr. Langdon grabbed the window cover, jumped out, and aimed towards the river
Who discover subatomic particle?
There are 3 subatomic particles in an atom, electrons, protons, and neutrons.
The first discovered was the electrons by J.J. Thomson in 1897.
The second discovered was the protons by Ernest Rutherford in 1919.
The third discovered was the neutrons by James Chadwick in 1932.
Is string theory the closest theory to a unified field theory?
Yes, so far it is- string theory explains many of the unresolved fundamental problems of our century, such as the opposition between Quantum Mechanics and Einstein's theory of general relativity.
What kinds of particles are made from quarks?
Both protons and neutrons are composed of quarks.
See the Web Links for more information
What is the name of subatomic particle named after Indian scientists?
The boson named after Indian physicist Satyendra Nath Bose is called "boson". It is a type of subatomic particle that follows Bose-Einstein statistics and is integral to the field of quantum mechanics.
Why is electricity sometimes described as a flow of electrons?
Flowing electrons makes electricity (they flow from negative to positive.
). You need a circuit or a path for the electrons to move through, a power source like a battery or a generator, and something to use the electricity, like a light bulb...
Particles are small pieces of matter. Depending on the context, it may refer to pieces of dust, to atoms or molecules, or to subatomic particles such as protons, electrons, quarks, etc.
Who invented the electron particle magnet?
Nicholas Morreau
Nicholas Morreau was a Soviet Scientist during 1943 who invented the first Electron Particle Magnet. He was never seen or heard of. He died at the age of 42 from Radiation and contamination while working on an experiment in his laboratory in 1948. His body was never found and he never married.
Yes, H20 is a covalent compound, therefore it shares electrons when it bonds.
What do electrons do in Bohr's model of atoms?
In Bohr's atomic model, electrons are in specific orbitals (NOT orbits), which are at specific energy levels. An electron can go directly from one orbital to another, but it can never be in-between any two orbitals. The energy level of these orbitals is specified by angular momentum being quantized.
The GUT theory is a theory that combines three of the four fundamental forces together. The three fundamental forces are the strong nuclear force, weak nuclear force, and electromagnetic force. This theory explains the connection between these forces and if gravity was able to connect with these forces, then we have the TOE (Theory of Everything).
How much neutrons does molybdenum have?
Most molybdenum atoms have 54 neutrons. The atomic number (number of protons) of molybdenum is 42, and its weight (number of protons and neutrons) is around 96. 96 - 42 = 54.
Can you use liquid nitrogen to freeze antimatter?
Most antimatter exists as subatomic particles produced either in radioactive decay or large particle accelerators. No significant quantities have been made and the only antimatter atoms ever produced have been antihydrogen. Any antimatter that came in contact with liquid nitrogen would annihilate both itself and part of a nitrogen atom, releasing energy that would heat the remaining liquid nitrogen.
If you could somehow produce a quantity of antimatter equal the the amount of liquid nitrogen, when they came in contact instead of cooling the antimatter there would be total annihilation of both materials resulting in an explosion on the order of teratons of TNT equivalent as the temperature of the products jumped to hundreds of millions of degrees kelvin to billions of degrees kelvin!!!!!
How many electrons can coexist in any given orbital?
The electon structure is 2,8,8. This means it can have a maximum of 2 electrons on its 1st shell, 8 on the 2nd and 8 on the 3rd :)
What are substances having no charge called?
Neutral particles.
An example is neutron found in the nucleus of an atom.
In what ways do electrons act like particles?
A: If a nucleus is a point like a flag pole then the electrons are orbiting this nucleus at a very big distance like football filed distance and they have a charge too
Why are images from an Electron Microscope in black and white only?
Because it uses electrons instead of light, and light is required for color to be present.
What is a proton pump inhibitor?
The proton pump inhibitors are a group of drugs that reduce the secretion of gastric (stomach) acid.
