Webelectron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 11,836the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton … WebElectron arrangement in atoms.

As we know, the positively-charged protons in the nucleus of an atom tend to attract negatively-charged electrons. While these electrons all stick within the atom because of their attraction to the protons, they also mutually repel each ... phmp texas
