  • Metals give electrons. Sodium has electronic configuration (2, 8, 1). It has only one electron in the outermost shell.
  • It can easily give a single electron in the outermost shell. Hence, Sodium is a strong metal.
  • Aluminium has an electronic configuration (2,8,3). It has three electrons in the outermost shell.
  • Donation of three electrons is more difficult than the donation of one electron. Hence, sodium is more metallic than aluminium.
