Question

Write the electron configuration for the following elements. Phosphorus (P) Cobalt (Co)

Answer 1

Explanation:

To write the electronic configuration of an atom, some principles must be followed.

Some these principles are:

• maximum number of electrons in the orbitals of sublevels are:

       two electrons for s-sublevel

       six electrons for p-sublevel

       ten electrons for d-sublevel

       fourteen electrons for f-sublevel

• Sublevels with lower energies are filled before those with higher energies according to Aufbau's principle
• No two electrons can have the same set of the four quantum numbers according to Pauli Exclusion principle.
• Hund's rule of maximum multiplicity states that electrons go into degenerate orbitals of sub-levels singly before pairing commences.

 Based on this:

    Phosphorus - 15   is 1s² 2s² 2p⁶ 3s² 3p³

    Cobalt - 27 is     1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁷ 4s²
