They have a different number of electrons in their outer shells.
They have different atomic numbers.
They have different number of electron shells.
They are different colors.
The property that transition metals have in common is that they usually have high melting points.
To find the answer, you can study the periodic table and examine the properties of transition metals. Transition metals are located in the d-block of the periodic table, specifically in the groups 3 to 12. They are known for their unique electronic configurations and partially filled d-subshells.
By researching the physical properties of transition metals, you will discover that they generally have high melting points compared to other metals. This is due to their strong metallic bonds, which are created by the attraction between the positive metal ions and the delocalized electrons in the metal lattice. The strong metallic bonds require a significant amount of energy to break, resulting in high melting points.
