Document Summary
Charge of the electron: -1. 6 x 10 19 c charge of the proton: 1. 6 x 10 19 c r = 5. 3 x 10 11 m. F = (9. 0 x 109 n m2/c2)(-1. 6 x 10 19 c)(1. 6 x 10 19 c)/(5. 3 x 10 11 m)2. The ratio of these two is 2. 26 x 1039 !! An incredibly large number, indicating how much stro(cid:374)ger coulo(cid:373)(cid:271)"s la(cid:449) is tha(cid:374) gra(cid:448)itatio(cid:374)al attraction. r. A substance in which electric charge can flow readily is called a conductor. One in which electric charge does not flow easily is called an insulator. Conduction in solids is done only by electrons. In metals, each atom gives up one (or more) electrons to the piece of metal as a whole. These electrons are no longer bound to any individual atom. Insulators, like glass or rubber, have each the electrons in each atom tightly bound to the atom.
