WebSep 12, 2024 · This model ignores the interactions between the electrons but respects the exclusion principle. For the special case of \(T = 0 \, K\), \(N\) electrons fill up the energy levels, from lowest to highest, two at a time (spin up and spin down), until the highest energy level is filled. The highest energy filled is called the Fermi energy. WebAnswer: We know, 1 mole = molecular mass (in gram) = 6.023 x 10^23 no. of atoms (Avogadro Constant) Molecular mass of Na is 23.
