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 determines the spin of a subatomic particle?
The spin of a subatomic particle is an intrinsic property that is not caused by the particle physically spinning on its axis. It is a fundamental characteristic of the particle that has a quantized value based on its quantum state. Spin is a crucial aspect of particle physics and plays a role in determining the particle's behavior in various interactions.
How break nucleus from proton?
Well, the question as asked does not actually make physical sense. No disrespect intended. You see, the 'proton' is itself regarded as the nucleus in the pure hydrogen atom (one + charge particle, the 'proton', and one - charge particle, the electron). As such, the 'proton' IS the nucleus.
In heavier elements the 'proton' is part of the nucleus when combined with a neutron.
Good luck in your search for knowledge. But better hard work than luck.
How many neutrons are in the isotope in 1-h-1?
There is 0 neutron in a Hydrogen-1 isotope. Hydrogen-1 has an atomic number of 1, which means it has 1 proton and no neutrons.
Can the higgs boson exist in a nebula?
No, the Higgs boson is a fundamental particle that exists within the framework of the standard model of particle physics. It is not a physical object that can exist in astronomical structures like nebulae.
Where are the nucleus and electron cloud found in a atomic structure?
The nucleus is found at the center of the atom and the electron cloud is found orbiting the nucleus at fixed, quantified radii.
Does Sr have a high electron affinity or a low electron affinity?
Sr has a relatively low electron affinity. Electron affinity is the energy change when an atom gains an electron to form a negative ion, and for strontium, this energy change is lower compared to other elements.
What region is an electron most likely to be found called?
The region in an atom where an electron is most likely to be found is called an orbital. Orbitals are defined as the three-dimensional spaces around the nucleus where electrons have the highest probability of being located.
How many valence electrons do atoms in period 1 have?
Hydrogen has 1 valence electron, whereas helium has 2 valence electrons.
What is a simple explanation for antimatter?
Antimatter is a type of matter that has the opposite properties of normal matter. When a particle of matter meets its corresponding antiparticle, they annihilate each other, releasing a large amount of energy in the process. Antimatter is rare in the universe and is mostly created in high-energy environments like particle accelerators.
What is the relative size of the 3 subatomic particles?
Protons and neutrons are about the same size and are larger than electrons. Protons and neutrons have a size of about 1 femtometer (10^-15 meters), while electrons are about 1000 times smaller.
What subatomic particle makes up the mass?
Protons and neutrons make up the mass of an atom. Electrons, which are negatively charged, are much smaller in mass compared to protons and neutrons.
What forces binds protons and electrons to form atoms?
Two oppositely charged particles (electron: - charge, proton: + charge) create an attractive electrostatic force described by Coulomb's Law.

How many electrons do halogen atoms get when they react?
Halogen atoms typically gain one electron when they react to achieve a stable electron configuration, forming a halide ion with a charge of -1. For example, chlorine (Cl) gains one electron to become Cl-.
What is the nature of space time at 1 picometer?
At a scale of 1 picometer, which is one trillionth of a meter, the nature of spacetime is still governed by the principles of general relativity, but quantum effects become significant. At such small distances, the concept of continuous spacetime breaks down, and a quantum theory of gravity is necessary to fully describe the nature of spacetime.
How many times is proton heavier than electron?
The ratio of a proton's rest mass to an electron's rest mass is 1836.15267247:1. For more information, follow the link below.
Is it true that Rubbing converts neutrons to protons increasing the charge?
No, rubbing does not convert neutrons to protons. Neutrons and protons are fundamental particles present in the nucleus of an atom and cannot be interconverted by rubbing. Rubbing may generate static electricity by transferring electrons between objects, but it does not change the fundamental composition of atomic nuclei.
How many number of protons and electrons for this atom or ion?
The atomic number tells you the number of protons. For instance oxygen has an atomic number of 8, and hence it has 8 protons. Electrons are slightly more complicated. In a neutral atom, the number of electrons is always the same as the number of protons. However, if the atom is charged (i.e. it is an ion), it may have more electrons than protons (negatively charged) or less electrons than protons (positively charged).
What is the electron dot formula for SF6?
The electron dot formula for SF6 would show 6 pairs of dots around the central Sulfur atom, representing the 6 Fluorine atoms bonded to it. The Sulfur atom will have 12 valence electrons around it in total.
How many neutrons does silicon 27 have?
Silicon-27 has 14 protons (since it is silicon) and 13 neutrons, as the atomic number (proton number) minus the mass number (proton number + neutron number) gives the number of neutrons. In this case, 27 - 14 = 13 neutrons.
Electrons are the subatomic particles found outside the center of the atom and are responsible for the chemical properties of the atom. Their arrangement in the electron cloud determines the reactivity, bonding, and other chemical behavior of the atom.
What are higher dimensions and what do they look like?
A higher dimension is exactly what it sounds like: a dimension that is different (higher) from length, width, and depth. Our world is in three dimensions, and a higher dimensional universe would have four or mroe dimensions.
Which subatomic particle is most responsible for chemical properties?
Electrons are the subatomic particles responsible for most chemical behavior (with the notable exception of nuclear chemistry), specifically the outer or valence electron shells.
The valence electrons are responsible mainly. But protons are responsible for nuclear reactions.
Who invented the negatively charged particle electron?
The negatively charged particle electron was discovered by J.J. Thomson in 1897 through his experiments with cathode rays. Thomson's experiments led him to propose the existence of the electron as a fundamental subatomic particle.
