Solution

Na+ have completely filled K and L shells:

  1. Sodium is a alkali metal. The main claim to fame of this substance is that it is one of the two components of table salt.
  2. Atomic number of Sodium (Na) = 11
    Number of electrons in Sodium (Na) = 11
    Sodium's [Na] electronic structure is 1s22s22p64s1.
  3. In order to form a positive ion, Naloses one electron. Therefore, Na+ ion possesses 10 electrons, which is one more than the Na atom. As a result, 2 electrons move to the K-shell and 8 to the L-shell, entirely filling both shells.
    The number of electrons in Na+is calculated as 11 - 1 = 10.
    Na to the power of plus signelectronic structure is 1s22s22p6
    K and L shells are thus fully filled in Na+.

Therefore, Na+ has completely filled K and L shells.
