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 the protons of cadmium?

The atomic number of Cadmium is 48, which is to say, it has 48 protons.

What does a laboratory probe do?

Laboratory probes allow you to examine the inside of the dissected organism further than just the surface.They also allow you to remove the internal organs of the dissected organism if needed.

Radiation resistance of quarter wave monopole antenna is?

The radiation resistance of quarter wave monopole is 36.5 ohms

Why is the Higgs boson particle important?

It's important because it's the particle that gives everything mass (kinda like weight) in Physics. If this particle doesn't exist, it means that all of the science we have relied on so far in Physics, is wrong. This includes Einstein's General Theory of Relativity, or the greatest work Einstein is known for (E=mc2). That's why it's important.

Why is grounding electricity so important?

Grounding is important, because it protects users of electricity from potentially fatal electrical shocks. This is accomplished through bolting, clamping or other effective mechanical means to provide an effective grounding path to the earth instead of through the user.

What is there in the empty space inside an atom except the electrons and their shells?

Nothing except for the force carrier particles that are responsible for all of the forces in the atom. These particles are called virtual particles and do not necessarily exist, but they are responsible for particle interactions. The space is simply that- space; it can be interpreted as a vacuum or simply said to be nothing.

What is the incoming energy source for electron transport chain?

The electron transport chain is the driving energy behind ATP synthesis. The energy itself comes from electron donors. In chloroplast, this donor's glucose.

What isotope has seven neutrons?

Carbon-13 has seven neutrons. It's rare, and is only 1% of all carbon atoms. Carbon has 6 protons, and usually 6 neutrons, however an extra neutron makes the mass of this isotope 13 amu or g/mol, hence its name.

Can string theory be proved?

Not with our level of technology, but the math is sound

Why did the path of only some alpha particles deviate in Rutherford experiment?

Alpha particles are positively charged helium nuclei. As such, they are repelled by other positively-charged nuclei. In Rutherford's experiment, he used gold foil. Since gold atoms have large, massive nuclei, the alpha particles were easily repelled by the large gold atom nuclei, and they were scattered in different directions.

How large is the Large Hadron Collider?

The LHC is a total of 27 kilometres (17 miles) long, running along the French - Swiss border. It is 3.8 metres wide.

How many electrons does clay have?

Clay consists of many different elements, and it is therefore impossible to tell how many electrons it has.

How are atoms and electrons related?

Atoms are made up of protons, neutrons, and electrons. They all balance each other out with their positive, negative, and neutral charges, while being in the atom!

If an atom has two protons would it be stable?

The atoms having 2 protons only in nucleus is not stable but 2 protons with 2 neutron in Helium nucleus are very stable.

What small subatomic particles are in the protons and neutrons?

The subatomic particles found in protons and neutrons are quarks. There are two types of quarks that combine to make either particle, up and down quarks. Protons are 2 ups and a down and neutrons are 2 downs and an up.

Why are the nuclear configurations of the actinides more important than their electron configurations?

The nuclear structure is more important because the nuclei of actinides are unstable and spontaneously break apart

How many neutrons do they have in thulium?

Thulium has 100 neutrons because its atomic number is 69 and atomic mass is 168.93 so if we subtract atomic no. by atomic mass ie. 168.93-69 we get the value 100.

How many protons neutrons and electrons are there in a molecule of water?

The number of neutrons will vary depending on the isotopes of hydrogen and oxygen in the molecule.

The number of protons and electrons will be 10 each in every molecule.
