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.
3,842 Questions
Are silver and gold both made of subatomic particles?
Yes, both silver and gold are composed of subatomic particles. At the atomic level, they are made up of protons, neutrons, and electrons. These subatomic particles combine to form the nucleus and electron cloud of an atom, determining its chemical and physical properties.
What holds the nucleus and electron cloud together in an atom?
strong nuclear force.
The nucleus is held together by both the strong nuclear force and the weak nuclear force. The electron is bond to the nucleus by electro-static forces.
The correct electron configuration for chlorine?
The correct electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5. This notation represents the distribution of electrons in the various energy levels and sublevels of the chlorine atom.
Are neutrinos smaller than a Planck Unit?
Yes, neutrinos are subatomic particles with a very small, non-zero mass. They are much larger than the Planck length, which is the scale at which quantum effects of gravity become important.
Which is bigger atom electron molecule or cell?
A cell is larger than a molecule, which is larger than an atom or an electron. Cells are the basic structural and functional unit of living organisms, while molecules are made up of atoms, and atoms are composed of even smaller particles such as electrons.
Which type(s) of subatomic particles can be located within the nucleus of an atom?
Protons and neutrons are the subatomic particles found within the nucleus of an atom. Electrons are found outside the nucleus in electron clouds.
Which subatomic particle has a greater mass a proton or an electron?
Proton has a greater mass than the electron.
How much energy does the large hadron collider produce?
That's a good question. Even the scientists at the LHC aren't sure. But generally, the protons produced in the hydrogen tanks (the tanks produce the beams that are shot at 99.9999999999999999999999999999999999% and so on of the speed of light) when in collision make a tremendous amount of power. But actually storing the power in A. dangerous B. very difficult. Hopefully with all of the power the collider sonsumes, CERN should find a way to give a little back...............................eventually anyway.
How many protons and neutrons are there in sodium?
11 protons and 12 neutrons for Na-23, the (only) naturally occurring isotope.
11 protons and 11 neutrons for Na-22, artificial isotope, 2.6 yr. halflife time
11 protons and 13 neutrons for Na-24, artificial isotope, 14.8 hr. halflife time
No, a kaon is a meson, not a baryon. Baryons are particles composed of three quarks, while mesons are composed of a quark and an antiquark. Kaons contain a strange quark and an anti-up or anti-down quark.
How many unpaired electrons does Si have?
Silicon (Si) has 0 unpaired electrons. It has a total of 4 valence electrons, which it shares to form covalent bonds with other atoms.
What subatomic particles represented the plums?
The plums in the famous "plum pudding" model of the atom represented electrons, which are negatively charged subatomic particles.
Does argon want to gain or lose electrons?
Argon is a Noble Gas. Thus it does not lose or gain electrons.
What two sub-atomic particles are located in the nucleus of the atom?
The two sub-atomic particles located in the nucleus of an atom are protons and neutrons. Protons carry a positive charge, while neutrons have no charge.
What indicates how strongly an atoms nucleus holds onto its valence electrons?
The measure of how strongly an atom's nucleus holds onto its valence electrons is known as electronegativity. Electronegativity increases across a period and decreases down a group in the periodic table. Atoms with high electronegativity tend to attract electrons more strongly than those with low electronegativity.
What are some examples of bosons?
Some examples of bosons are photons (particle of light), W and Z bosons (mediate weak nuclear force), gluons (mediate strong nuclear force), and Higgs boson (associated with giving mass to particles).
What is name of the force among the molecules of matter?
The name of the force present in all molecules that results from the movement of electrons is called London dispersion forces. The force of attraction between the positive end of one molecule and the negative end of another molecule is dipole .
Which 2 subatomic particles are found in the nucleus?
The two subatomic particles found in the nucleus are protons and neutrons. Protons have a positive charge, while neutrons have no charge.
What are the number of protons and neutrons in aluminum?
There are 13 protons and 14 neutrons in the nucleus of an aluminum atom.
The number of protons is the same as the atomic number and the number of neutrons is just the mass number - atomic number. In a stable atom anyway, there's different isotopes which is where there is a different number of neutrons, but if it doesn't specify then this is what it is.
What is a subatomic particle without charge?
A subatomic particle without charge is a neutron. Neutrons are neutral particles found in the nucleus of an atom alongside protons. They do not possess any electric charge, unlike electrons which are negatively charged and protons which are positively charged.
The question is: What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?
This question may seem hard and/or confusing, but it's really not. You just have to think about it for a minute. This question was in my science quiz online. I had to take LOTS of notes, and guess what?, the answer was right there in my notes..
The notes that I took for this question had the topic:Electrons in an Element
My notes were:
-Electrons occupy the electron cloud.
-Each electron occupies an energy state.
-Electrons farther from the nucleus occupy a higher energy state.
-The electron cloud is divided into energy levels.
-Each energy level can hold a certain number of electrons
-Valence Electrons are usually found in the highest energy level.
Not very much notes, but lots of information, and most of them are about energy, and one is about Valence electrons. So, let's figure this.
If a valence electron usually have the highest energy level, then a nonvalence electron must not have any energy levels. So, what you would have to add to the nonvalence electron is add energy to become a valence electron.
Our question is: What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?
So the answer to our question is: Energy. Energy can be added.
Where do you find the neutrons on the element?
Neutrons are found in the atomic nucleus of an element, along with protons. They have no electrical charge and help stabilize the nucleus. The number of neutrons in an element can vary, leading to different isotopes.
The movement of which subatomic particle causes an electric motor to run?
Eectrons moving in the wire that is why it is called electricity. Electrons moving in a circle around the iron core called the armature produces a magnetic field. This produces a north and south pole. The poles of the armature are attracted to the opposite poles of the magnets, causing the armature to spin.
