Explanation:
The second series of transition elements starts with Ytterium (Y).

Transition Elements:
Transition elements are a group of elements in the periodic table that have partially filled d orbitals in their ground state or stable oxidation state. They are located in the middle of the periodic table between the s-block and p-block elements.

Series of Transition Elements:
The transition elements are divided into four series based on the filling of 3d, 4d, 5d, and 6d orbitals. These series are called the first series, second series, third series, and fourth series, respectively.

First Series:
The first series of transition elements starts with Scandium (Sc) and includes the elements from Scandium to Zinc (Zn). These elements have the outer electronic configuration of (n-1)d1-10 ns1-2.

Second Series:
The second series of transition elements starts with Ytterium (Y) and includes the elements from Ytterium to Cadmium (Cd). These elements have the outer electronic configuration of (n-1)d1-10 ns1-2.

Third Series:
The third series of transition elements starts with Lanthanum (La) and includes the elements from Lanthanum to Mercury (Hg). These elements have the outer electronic configuration of (n-2)f0-14 (n-1)d0-1 ns2.

Fourth Series:
The fourth series of transition elements starts with Actinium (Ac) and includes the elements from Actinium to Copernicium (Cn). These elements have the outer electronic configuration of (n-2)f0-14 (n-1)d0-1 ns2.

Therefore, the second series of transition elements starts with Ytterium (Y) and not with Scandium (Sc), Rhodium (Rh), or Actinium (Ac).
