Question

What are the differences between the first row and the
other two rows of transition metals

Answer 1

Answer:

Furthermore, the elements of the first transition series contain a complete Argon electron configuration with 3d and 4s electrons. However, the second transition series contains a complete Krypton electron configuration with 4d and 5s electrons.

Hope it helps you

Answer 2

The first transition series elements have a 3d outermost d orbital, while the second transition series elements have a 4d outermost d orbital, and the third transition series elements have a 5d outermost d orbital.

Elements:

• The elements yttrium (symbol Y, atomic number 39) through cadmium make up the second series (symbol Cd, atomic number 48).
• (Atomic number 48, symbol Cd) The third group includes lanthanum (symbol La, atomic number 57) and mercury (symbol Hg) (symbol Hg, atomic number 80).
