Title: Gd Explained: Understanding Gadolinium (Element) and Gdansk (City)
Meta Description: Discover the dual meaning of “Gd”—exploring the rare earth element Gadolinium and the historic Polish city of Gdansk. Learn uses, facts, and why both matter.
What is Gd? Unpacking the Term
“Gd” is an abbreviation that commonly refers to two distinct subjects:
- Gadolinium (Gd): A chemical element in the periodic table, part of the lanthanide series.
- Gdańsk (Gd.): A major port city in northern Poland, rich in history and culture.
This article dives into both meanings, clarifying their significance and relevance.
Gadolinium (Gd): The Rare Earth Metal
Properties & Discovery
- Atomic Number: 64
- Discovery: Swiss chemist Jean Charles Galissard de Marignac in 1880.
- Naming: Honors Finnish chemist Johan Gadolin, a pioneer in rare earth research.
- Key Traits: Silvery-white, malleable, magnetic at room temperature, and highly neutron-absorbent.
Applications & Uses
Gadolinium’s unique properties make it vital across industries:
