16 gru 2021 · In 14.009 (Economics and Society's Greatest Problems), a first-year class taught by Nobel laureates, MIT students discover the power of economics to help solve major societal problems.
8 gru 2018 · An electron is a stable subatomic particle with a negative electrical charge. Unlike protons and neutrons, electrons are not constructed from even smaller components. Each electron carries one unit of negative charge (1.602 x 10 -19 coulomb) and has a very small mass as compared with that of a neutron or proton.
The electron (e −, or β − in nuclear reactions) is a subatomic particle with a negative one elementary electric charge. [13] Electrons belong to the first generation of the lepton particle family, [14] and are generally thought to be elementary particles because they have no known components or substructure. [1]
1 paź 2024 · Electron, lightest stable subatomic particle known. It carries a negative charge of 1.6 x 10^-19 coulomb, which is considered the basic unit of electric charge. The electron was discovered in 1897 by the English physicist J.J. Thomson during investigations of cathode rays.

The electron is a subatomic particle that is found in all atoms. Unlike protons, neutrons, or the nuclei of atoms, electrons are elementary particles. This means they are not made of even smaller particles. Also unlike protons and neutrons, electrons have essentially no mass.
