In physics, a subatomic particle is a particle smaller than an atom. [1] ... atoms and molecules, and their structure and interactions, requires quantum mechanics.
The subatomic scale is the domain of physical size that encompasses objects smaller than an atom.It is the scale at which the atomic constituents, such as the nucleus containing protons and neutrons, and the electrons in their orbitals, become apparent.
Atoms are the smallest neutral particles into which matter can be divided by chemical reactions. An atom consists of a small, heavy nucleus surrounded by a relatively large, light cloud of electrons. An atomic nucleus consists of 1 or more protons and 0 or more neutrons. Protons and neutrons are, in turn, made of quarks.
At distances smaller than 2.5 fm this force is much more powerful than the electrostatic force that causes positively charged protons to repel each other. [43] Atoms of the same element have the same number of protons, called the atomic number. Within a single element, the number of neutrons may vary, determining the isotope of that element.
The smallest particles are the subatomic particles, which refer to particles smaller than atoms. [9] These would include particles such as the constituents of atoms – protons , neutrons , and electrons – as well as other types of particles which can only be produced in particle accelerators or cosmic rays .
Rather than existing as a 1 or a 0 like a bit, qubits can exist as a 1 and 0 or any combination of the two at the same time, thanks to what is called superposition.
Muonic hydrogen atoms are much smaller than typical hydrogen atoms because the much larger mass of the muon gives it a much more localized ground-state wavefunction than is observed for the electron. In multi-electron atoms, when only one of the electrons is replaced by a muon, the size of the atom continues to be determined by the other ...
