Question

Write the first transition series in perodic table?

Answer 1

The First Transition series of the Periodic table lies in the 4th period. It is also called as 3d series.

The elements in this series are ⇒

• Scandium
• Titanium
• Vanadium
• Chromium
• Manganese
• Iron
• Cobalt
• Nickel
• Copper
• Zinc

These elements have the general electronic configuration as,  (n - 1)d¹⁻¹⁰ ns⁰⁻².

Hope it helps.

Answer 2

First transition series : The series which is start from scandium (Sc-21) to zinc (Zn- 30) and the last electron of the element are entered in a 3d subshell is known as 3d series or first transition series .
General electronic configuration of transition elements is (n- 1)1-d, ns0-2
It contain 10 elements of 4th period in modern periodic table

Elements are first transition series:
