Final answer:
Transition elements are characterized by having an incomplete d subshell, are found in the d-block of the periodic table, and form colorful compounds. Five examples include Iron (Fe, atomic number 26), Copper (Cu, 29), Yttrium (Y, 39), Silver (Ag, 47), and Rutherfordium (Rf, 104).
Step-by-step explanation:
Transition elements, also known as transition metals, are elements found in the d-block of the periodic table and are characterized by having an incomplete d subshell. These elements are known for their unique electron configurations and the colorful compounds they form. Below is a list of five different transition elements along with their chemical symbols and atomic numbers:
- Iron (Fe) - Atomic number: 26
- Copper (Cu) - Atomic number: 29
- Yttrium (Y) - Atomic number: 39
- Silver (Ag) - Atomic number: 47
- Rutherfordium (Rf) - Atomic number: 104
These elements are known for their unique electron configurations, which involve the addition of electrons to the d subshell. This is the defining feature of the transition elements and the reason why they are often referred to as "d-block" elements. Additionally, many transition element compounds display bright colors due to the d-d electronic transitions that occur when they absorb visible light.
