ELECTRON (ALL Govt job )
Electron (All Govt Jobs MCQ) ELECTRON A subatomic particle having a negative electric charge is called an electron.It is one of the fundamental constituents of matter, primarily found in the electron cloud surrounding the nucleus of an atom. Electrons are much lighter than protons and neutrons, with a mass approximately 1/1836 that of a proton. In atoms, electrons occupy discrete energy levels or orbitals, and their arrangements determine the chemical properties of elements. Electrons can also exist as free particles, and their behavior is described by quantum mechanics, exhibiting both particle-like and wave-like properties. Sure, let's dive deeper into the details about electrons: 1. Basic Properties : - ** Charge **: An electron carries a fundamental unit of negative charge, denoted as \( -1e \), where \( e \) is the elementary charge (approximately \( -1.602 \times 10^{-19} \) coulombs). - ** Mass **: The mass of an electron is approximately...
