Question

Transition Metals Have The General Electronic Configuration

Answer 1

d-block elements

• The elements that lie in the middle of s and p- block elements are called transition elements.
• These elements' outermost s-shell contains one or two electrons (ns).
• But the last electron usually enters the penultimate d-shell, hence called d-block elements.
• Thus the general electronic configuration is $(\mathrm{n}-1){\mathrm{d}}^{1-10},{\mathrm{ns}}^{1-2}$.
