SpletFirst, the electron number density (last row) distribution drops off sharply at the Fermi energy. According to the theory, this energy is given by EF = h2 8me(3N πV)2/3. 9.31 Fermi energies for selected materials are listed in the following table. Table 9.3 Conduction Electron Densities and Fermi Energies for Some Metals SpletWe are given the density of copper, 8.80 × 10 3 kg/m 3 8.80 × 10 3 kg/m 3, and the atomic mass of copper is 63.54 g/mol 63.54 g/mol. We can use these two quantities along with …
SpletFor copper, n = 8.5 × 10 28 per m 3 The charge on an electron, Q = 1.6 × 10 -19 C So, I = n A v Q 5 = 8.5 × 10 28 × 0.5 × 10 -6 × v × 1.6 × 10 -19 5 = 27 200 v v = 7.35 × 10 -4 m s -1 So, for this current, the drift velocity of electrons is about a tenth of a millimetre per second: pretty slow! Question 5 SpletAtomic Number – Protons, Electrons and Neutrons in Helium. Helium is a chemical element with atomic number 2 which means there are 2 protons in its nucleus.Total number of …
