Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

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

1. What is the technological relevance?Crucial for semiconductor fabrication, advanced microscopy, and materials science requiring atomic-level precision
2. How many picometres are in a nanometre?One nanometre equals 1,000 picometres.
3. Why do scientists use picometres?Scientists use picometres to measure very tiny distances inside atoms and molecules, helping them understand how matter is built. It lets them compare measurements from different experiments accurately.

International System of Units (SI): The modern form of the metric system, providing a coherent framework for scientific measurement globally.
Atomic Radius: Half the distance between the nuclei of two identical atoms bonded together.
X-ray Crystallography: A technique used to determine the atomic and molecular structure of a crystal by analyzing its diffraction patterns.
