General outer electronic configuration of transition elements

Short answer

The general outer electronic configuration of transition elements is (n−1)d¹⁻¹⁰ ns¹⁻².

Write the general outer electronic configuration of transition elements.

The general outer electronic configuration of transition elements is (n−1)d¹⁻¹⁰ ns¹⁻².

For the 3d series this is 3d¹⁻¹⁰ 4s¹⁻² (for example Fe: 3d⁶ 4s²). Pd is an exception, with 4d¹⁰ 5s⁰.
