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.

What is singularity in physics?
In Physics, singularity is a point at which a function takes an infinite value, especially in space-time when matter is infinitely dense, as at the center of a black hole.
What do you get when you combine neutrons and protons?
When you combine neutrons and protons you get an atomic nucleus.
What enables the scientists to come up with new technology?
Education, creativity, experimentation and research.
It would release energy. It had to absorb it in order to get from 2 to 3. Law of conservation of energy says it must now release it to fall back.
elementary particles are generally divided into two groups: Hadrons, which are made up of quarks (three for baryons (ie. protons and neutrons), and two for muons), and the second group called Leptons (ie. electrons and neutrinos). there are also the force carrying particles: gluons (strong force), gravitons (gravity), W-bosons (weak force), and photons (electro-magnetivity) though as far as i am aware only photons have been observed and the rest are only theoretical.
Does oxygen-18 have 18 protons?
No. Oxygen always has 8 protons. Oxygen 18 has 8 protons and 10 neutrons (8 + 10 = 18)
What are examples of mesons and baryons?
Baryons are particles composed of three, "color-neutralizing" quarks. Protons and neutrons are the most well-known examples.
Mesons are particles composed of a quark/antiquark pair. The pion is the best-known example.
How many electrons does phosphorus give or take?
phosphorus will accept 3 electrons or share 3 electrons
There are 6 different flavors of quarks. They are called up, down, strange, charm, top, and bottom. Their charges are +2/3, -1/3, -1/3, +2/3, -1/3, and +2/3 respectively.
What could be in the higs Boson?
The Higgs Boson, if it exists, should be a massive point particle, so there should be nothing "in" it.
How many electrons does sulfar have?
Sulfur is a non metal element. There are 16 electrons in a single atom.
How many delocalised electrons are there in a coulomb?
6.24151 × 1018 electrons have a charge of minus one coloumb (the coloumb is defined in terms of positive charge). I don't know what you mean by "delocalized", but normally all electrons have the same charge.
Do the electron cloud orbit like the sun?
First, recall that planets orbit the sun, not the other way around. Secondly, the term electron cloud is used to describe the body of electrons that orbit the nucleus of an atom. To answer your question as succinctly as possible, the analogy of planets orbiting the sun is one of the best to consider when thinking about the orbit of electrons
The BBC show titled "the six billion dollar experiment" announced that the LHC will be switched on in Oct, 2007. But the schedule has slipped a year to Oct, 2008. So I guess the total cost will be around 7 billion.
Do protons of an element vary?
All atoms of the same element have the same number of protons.
Atoms of different elements have different numbers of protons.
The number of protons determines the element.
What species are formed by the decay of neutron?
electron and neutrino are formed by the decay of neutron.
What the loss of an electron is called?
When a molecule loses an electron, it is said to be oxidized. The process is reduction.
What it the electron geometry for PF3?
The electron geometry ("Electronic Domain Geometry") for PF3 is tetrahedral.
The molecular geometry, on the other hand, is Trigonal Pyramidal.
Are valence electrons located in the electron cloud?
The outermost shell of an electron is called the valence shell. This shell may or may not have electrons.
The valence shell is a part of the electron cloud.
So your answer is
Yes, the valence electrons are located in the electron cloud.
What causes static electricity?
How does static electricity work?
1. Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit. The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons. The electrons cling to your body until they can be released. As you reach and touch your pet (dog or cat) you get a shock. It is only the extra electrons being released from you to your unsuspecting pet.
How does my hair stick up?2. As you remove your hat, electrons are transferred from hat to hair, creating that interesting hairdo! Remember, objects with the same charge repel each other. Because they have the same charge, your hair will stand on end. Your hairs are simply trying to get as far away from each other as possible! How does a balloon stick to the wall?3. When you rub a balloon against your clothes and it sticks to the wall, you are adding a extra of electrons (negative charges) to the surface of the balloon. The wall is now more positively charged than the balloon. As the two come in contact, the balloon will stick because of the rule that opposites attract (positive to negative).
