D Block Elements in Periodic Table
D-block elements are strategically located between the s-block and p-block elements in Periodic Table. This central position reflects their transitional role in the periodic table, connecting elements with distinct chemical behaviours.
Example of d Block Elements
Scandium (Sc): Scandium is a d-block element appreciated for its lightweight and high strength. It is used in aerospace applications, where its combination of properties makes it an ideal choice for lightweight structural components in aircraft.
Vanadium (V): Vanadium finds use in steel alloys, where its addition enhances strength and corrosion resistance. It’s commonly used in manufacturing high-strength steel for applications like tools, springs, and engine components.
Titanium (Ti): Titanium is known for its remarkable strength-to-weight ratio and corrosion resistance. It’s extensively used in aerospace and medical implants due to its biocompatibility, as well as in sports equipment, such as bicycles and golf clubs.
Chromium (Cr): Chromium’s ability to resist corrosion is a key component in stainless steel production. This type of steel is used in various applications, including kitchen appliances, cutlery, and architectural structures.
Iron (Fe): Iron, one of the most abundant d-block elements, plays a pivotal role in the production of steel used in construction, transportation, and machinery. Additionally, iron is vital in transporting oxygen in the bloodstream as part of haemoglobin.
Zinc (Zn): Zinc is widely used as a protective coating for iron and steel to prevent corrosion. It’s used in galvanization processes for structures like bridges, electrical towers, and automotive parts.
Manganese (Mn): Manganese is a critical element in steel production, where it helps remove impurities and improve the strength and durability of steel. It’s also used in the production of aluminium alloys.
Gold (Au): Gold is known for its beauty and resistance to corrosion. It is highly prized in jewellery and as a store of value, often used in coins and bullion.
Mercury (Hg): Mercury’s unique property of being a liquid at room temperature finds application in barometers, thermometers, and some electrical switches. However, its toxicity has led to a decline in its use in recent years.
d Block Elements
D-block elements are the elements in which the last electron enters the d subshell. d Block elements are situated at the middle of the periodic table, and act as a bridge between metal and non-metals in the periodic table. These elements, also known as transition elements, play a significant role in shaping our fundamental understanding of chemical principles.
In this article, we will learn about d-block elements in detail exploring their electron configurations, providing examples along with their properties and applications, and examining their historical context.
