Rare Earth Elements on the Periodic Table: Terbium & More—Driving Sustainable Agriculture and Technology in 2025
“Only 17 rare earth elements, including terbium, power over 90% of advanced agricultural technologies in 2025.”
Introduction: Rare Earth Elements on the Periodic Table and Their Modern Rise
Rare earth elements on the periodic table have changed the face of modern technology, agriculture, and sustainable systems. Despite their name, these elements are not always “rare”—their dispersed presence in Earth’s crust means access is a intricate puzzle of mining, extraction, and supply chain management. As of 2025 and beyond, understanding how these uncommon elements periodic table entries like terbium, neodymium, and dysprosium impact every facet of our world is pivotal for innovation and environmental resilience.
The role of rare earth elements (REEs) in undergirding society—powering our clean energy technologies, defence systems, and cutting-edge agriculture—is increasingly critical. The demand for REEs is exploding, and the quest for responsible management and strategic resource allocation is at the core of contemporary global policy and business.
In this in-depth guide, we unpack the properties, applications, and challenges surrounding these vital elements, with a special emphasis on terbium (Tb, atomic number 65) and its sustainable agriculture and technology implications through 2026 and beyond.
Understanding the Group: The 17 Rare Earth Elements in the Periodic Table
The rare earth elements on the periodic table are not a monolith. This group is made up of 15 lanthanides (atomic numbers 57–71) plus scandium and yttrium. Together, these chemically similar elements have transitioned from being scientific curiosities to becoming critical for the technological progress of the 21st century.
