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.

When were Particle accelerators first developed?
Particle accelerators were first developed by John D. Cockcroft and Ernest T. S. Walton in 1932
Comes in two flavors positive and negative?
Electric charge can be positive or negative both on large scales and fundamentally (eg the protons in atomic nuclei have a charge of +1 and the electrons that orbit those nuclei have a charge of -1 [units are arbitrary, if you want derived SI then these charges are +- 1.6*10^-19 C]).
You can also think of magnetic north and south poles as being 'positive' and 'negative' although this isn't strictly true.
Mathematically of course there are positive and negative numbers where the number -x is defined by the fact that x+(-x)=0.
The difference between holes and electron is that?
The electron, as modeled by Alexander Burinskii, is gravitationally confined however its ring singularity is described as "naked". The electron angular momentum is too great to allow complete gravitational collapse to its Schwarzschild radius. This means that its ring singularity is not hidden behind an event horizon and so is naked. It does not collapse to undefined or infinite density. It has some, but not all of the properties that a black hole is expected to have.
Further evaluation indicates electron gravitational collapse is halted at its gravitational photon orbit radius. This radius has a non-zero size so the undefined or infinite density problem is avoided.
What starts with a q and makes up protons electrons nuetrons?
Quarks are one type of matter particle. Most of the matter we see around us is made from protons and neutrons, which are composed of quarks.
Why electrons are typically not included when determining the mass of an atom?
its because they are extremely small
Why there is no charge on neutron?
Neutrons have no charge because they are made up of smaller particles, called quarks, which carry fractional charges that, when combined, add up to zero. There is one up quark and two down quarks in a neutron. The up quark has a fractional elementary charge of +2/3 while each down quark's charges are -1/3. If you add those charges up, +2/3 - 1/3 - 1/3, you get zero.
Ion that have 41 proton and 39 electron?
It will be Nb2+ or Niobium(II) ion, as the atomic number of niobium is 41.
(Note: Initially molybdenum was given as the answer. But the atomic number of Mo is 42 and not 42).
How many neutrons does suflur have?
Sulfur has 16 neutrons. To find out how many neutrons an element has you subtract the atomic number of that element by the atomic mass. omg thank you so much

What is the subatomic structure of a Meson?
A Meson is a subatomic particle that comprises of 1 quark and 1 anti-quark.
The concept of atoms, or particles that make up all of matter, is an ancient one. However, John Dalton came up with the first scientific atomic theory in the early 1800s.

Bosons and Fermions are parts of Quaternion Electronic Particles. The Boson is the Quaternion Scalar part and the Fermion is the Quaternion Vector part. Quaternions are four dimensional "particles" a Boson and a three dimensional Fermion
The Quaternion Unit can be described by Q= Cos(Spin) + v Sin(Spin) where v is the unit vector. The Quaternion consists of a scalar part the Boson = Cos(Spin) and a vector part the Fermion = v Sin(Spin).
When the angle Spin = n pi/2 i
f n is a multiple of 1 then the Quaternion Unit is a positive Fermion;
If n is a multiple of 2 then the Quaternion is a negative Boson;
if n is a multiple of 3 then the Quaternion is a negative Fermion
if n is a multiple of 4, then the Quaternion is a Positive Boson.
In general Bosons are even spin angles of pi/2 and Fermions are odd spin angles of pi/2.
If the spin angel is not a multiple of pi/2 then the Quaternion is the sum of a Boson and a Fermion.
This looks like Complex Numbers. because it is. Complex Numbers are a Quaternion 2 dimensional subgroup with Boson and a single vector Fermions.
What is a name for all the subatomic particles?
There are many many subatomic particles, the main three are protons, neutrons, and electrons.

What is the electron dot formula for M?
There is no element symbolized as "M". If you find M in a chemical formula or equation, it most likely means any metal element (i.e., iron, silver, etc). There are three metals which begin with M: magnesium (Mg), manganese (Mn) and molybdenum (Mo).
What is the difference between protons neutrons and electrons can I please have a simple answer?
Protons and neutrons have approximately the same mass, but the proton is electrically charged and the neutron isn't. Electrons have a much much lower mass and an opposite electrical charge to that of the proton.
That's about as simple as I can get it. It's by no means the only difference between them.
What is a chemical change in which electrons are gained?
A chemical change in which electrons are gained is a reduction.
How many superstrings compose 1 electron?
String theory, including those that satisfy super-symmetry (ie, super-string theories), takes as axiomatic that all particles -- electrons, gravitons, anti-quarks, etc -- are best represented mathematically as one string vibrating in several dimensions.
In other words, one electron means one string.
How come the universe is made of matter and not antimatter?
That is not currently known. There is a slight assymetry between matter and antimatter, but so far, it seems that this assymetry is not enough to explain why there is only matter, and hardly any antimatter, in the Universe. Without such an assymetry, there wouldn't be either matter or antimatter in the Universe - just radiation. For more information about what is known, and what isn't, check the Wikipedia article on "Baryon asymmetry".
