Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who discovered Perovskite (structure)?1839
2. How big is Perovskite (structure)?Improving long-term stability and developing lead-free alternatives
3. What is the formula?ABX3
4. What is the discoverer?Gustav Rose
5. What is the perovskite structure and what does ABX3 mean?The perovskite structure is a special arrangement of atoms in a cube. It follows the formula ABX3, where A and B are metal atoms and X is a nonmetal like oxygen or a halogen. This pattern lets scientists change the atoms to create different properties.
6. Where was the mineral perovskite first found?The mineral perovskite, calcium titanate, was first found in 1839 in the Ural Mountains in Russia. It was named after the mineralogist L. A. Perovski.
