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 key applications?Lasers, semiconductors, atomic clocks, MRI, quantum computing, and advanced spectroscopy
2. How do electrons move around the nucleus?Electrons don't travel in neat circles like planets. Instead, they exist in probability clouds called orbitals, each with a specific energy level.
3. Why do atoms give off light when they change energy levels?When an electron jumps to a higher energy level, it needs extra energy. When it falls back down, it releases that energy as light, producing a unique spectrum for each element.

Quantum Mechanics: The fundamental theory describing nature at the smallest scales of energy and matter.
Atomic Spectra: The unique patterns of light emitted or absorbed by atoms, serving as their 'fingerprints'.
Electron Orbitals: Regions around an atom's nucleus where electrons are most likely to be found, defined by quantum numbers.
