Question

The general electronic configuration of transition elements is ______.

Options

• `(n - 1) d^{1 - 5)`

• `(n - 1) d^(1 - 10) ns^1`

• `(n - 1) d^(1 - 10) ns^2`

• none

Answer 1

The general electronic configuration of transition elements is `bbunderline((n - 1) d^(1 - 10) ns^2)`.

Explanation:

Transition elements have electrons filling the (n − 1)d orbitals, while the outermost shell contains ns² electrons. So, the general electronic configuration of transition elements is `(n - 1) d^(1 - 10) ns^2`. These electrons are responsible for their variable oxidation states, magnetic properties, and formation of coloured compounds.
