Has supersymmetry been experimentally confirmed? What are extra spatial dimensions and how might they be detected?

Sep 3, 2020 ... All matter is composed of atoms, and atoms are composed of three smaller subatomic particles: protons, neutrons, and electrons. A subatomic particle is a particle smaller than an atom. Like atoms and molecules, a subatomic particle is far too small to be seen with the eye. Atoms are composed of three main subatomic particles: protons, neutrons, and electrons. · Protons and neutrons are grouped together in the nucleus of an atom, ... For example, a carbon atom has six protons, but an atom with only five protons is boron while an atom with seven protons is the element nitrogen. Neutrons are ... Aug 13, 2018 ... The nucleus of an atom is packed with protons and neutrons, though not quite as densely as in neutron stars. Occasionally, if they are close ... Isotopes are atoms of the same element that have the same number of protons (ie, atomic number, "Z") but a different number of neutrons. The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is ... Typically, an atom can be broken down into three subatomic particles, namely: protons, electrons, and neutrons. What are Subatomic Particles? For a long time, ... The Atomic Structure · The nucleus, at the atom's center, contains protons and neutrons. · Protons are positively charged particles, while neutrons have no charge ... Jan 17, 2016 ... Yes! However, it very much depends on what you mean by atoms. For example - as ACuriousMind above mentioned, one of the more common ones is muonium.
