Identifying the Transition Metals- Which of the Following Elements Belongs to This Unique Class-

Which of the following is a transition metal? This question often arises in the field of chemistry, particularly when discussing the periodic table and the properties of elements. Transition metals are a unique class of elements that exhibit a range of fascinating characteristics, making them indispensable in various industries and scientific research. In this article, we will explore the defining features of transition metals and identify which of the given options qualifies as a transition metal.

Transition metals are located in the d-block of the periodic table, which is situated between the s-block and p-block elements. They are known for their variable oxidation states, ability to form colored compounds, and high melting and boiling points. Some of the most common transition metals include iron, copper, gold, and silver.

Now, let’s examine the options provided to determine which one is a transition metal:

1. Carbon (C) – Carbon is a nonmetal and belongs to the p-block of the periodic table. It is not a transition metal.

2. Sodium (Na) – Sodium is an alkali metal and is located in the s-block of the periodic table. It is not a transition metal.

3. Iron (Fe) – Iron is a well-known transition metal. It is located in the d-block of the periodic table and exhibits the characteristic properties of transition metals, such as variable oxidation states and the ability to form colored compounds.

4. Chlorine (Cl) – Chlorine is a halogen and is located in the p-block of the periodic table. It is not a transition metal.

Based on the given options, the correct answer to the question “Which of the following is a transition metal?” is iron (Fe). Iron’s unique properties and its importance in various applications, such as construction, manufacturing, and even in the human body, highlight the significance of transition metals in science and industry.
