WebDec 24, 2015 · Electrons are the subatomic particles that orbit the nucleus of an atom. They are generally negative in charge and are much smaller than the nucleus of the atom. If you wanted a proper size... WebProtons and neutrons are in the center of the atom, and they make up the nucleus. Protons have a positive charge. Neutrons have a neutral charge (no charge). Electrons have a negative charge, and are far away from the nucleus. The charge on the proton and electron are exactly the same in magnitude, but opposite in sign.

WebAn electron, symbol e −, is one of the fundamental particles that make up matter. The electrons are negatively charged (-1e), almost massless particles that nevertheless account for most of the size of the atom. Their rest mass equals 9.109 × 10 −31 kg ( 510.998 keV/c2) (approximately 1/1836 that of the proton). In the Standard Model of particle physics, electrons belong to the group of subatomic particles called leptons, which are believed to be fundamental or elementary particles. Electrons have the lowest mass of any charged lepton (or electrically charged particle of any type) and belong to the first-generation of fundamental particles. The second and third generation contain charged lepto… dfer muriel bowser

WebThe number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Phosphorus is 15. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom. WebElectrons are much smaller in mass than protons, only about 1/1800 of an atomic mass unit, so they do not contribute much to an element’s overall atomic mass. On the other hand, electrons do greatly affect an atom’s charge, as each electron has a negative charge …
