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. Who discovered Hydrogen atom?1766 by Henry Cavendish
2. What is the scientific name?Hydrogen atom
3. Why does the electron stay around the proton instead of falling in?The opposite charges of the proton and electron attract each other. In quantum mechanics, the electron can only stay in certain energy levels, so it doesn’t spiral into the proton.
4. How does hydrogen light up stars?In stars, hydrogen atoms fuse together to make helium. This fusion releases huge amounts of energy that makes stars shine and keeps galaxies bright.

Baryonic Mass: The mass contributed by protons and neutrons, which form the 'normal' matter in the universe.
Atomic Spectroscopy: The study of how atoms absorb and emit light, revealing their energy levels and composition.
Quantum Mechanics: The fundamental theory in physics describing nature at the smallest scales of energy and matter.
Nuclear Fusion: A reaction where atomic nuclei combine to form heavier nuclei, releasing immense energy.
