Sodium has atomic number Z= 11 and in the ground state its electrons fill the orbitals as$\tau$$\mathbf{v}_d = -e\mathbf{E}\tau /m$$I$$\mathbf{j} = \mathbf{I}/A = -ne\mathbf{v}_d = ne^2\mathbf{E}\tau /m$$n$$A$$\mathbf{j} = \sigma \mathbf{E} = \mathbf{E}/\rho$$\sigma = ne^2 \tau /m$$\rho = m/ne^2\tau$$C$$T^3$$T^3$$T^3…
