Charge density many of them in a macroscopic volume (there are about 10 conduction electrons in a cubic centimeter of copper) the continuous approximation is very accurate when applied to macroscopic volumes, and even microscopic volumes above the nanometer level. At atomic scales, due to the uncertainty principle of quantum mechanics, a charged particle does not "have" a precise position but is represented by a probability distribution, so the charge of an individual particle is not concentrated at a point but is 'smeared out' in space and acts like a true continuous charge distribution. This is the meaning of 'charge distribution' and
John (given name) masculine name in the United Kingdom, but by 2004 it had fallen out of the top 50 names for newborn boys in England and Wales. By contrast Jack, which was a nickname for John but is now established as a name in its own right, was the most popular name given to newborn boys in England and Wales every year from 1995 to 2005.
