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 model type?Early quantum mechanical model of the atom
2. What is the primary proponent?Niels Bohr
3. What is the Bohr model of an atom?It shows electrons moving in special, fixed orbits around the nucleus, like tiny planets around a sun. These orbits are only certain sizes and energies, so electrons don't lose energy and fall into the nucleus.
4. Why did Niels Bohr create his model?He wanted to fix a problem with earlier models that said electrons would spiral into the nucleus. By using quantum ideas, he made electrons stay in stable orbits.

Quantization: The principle that certain physical properties, like energy, can only exist in discrete, specific amounts or values.
Stationary States: Allowed energy levels or orbits in the Bohr model where electrons do not radiate energy.
Photon: A fundamental particle of light, carrying a specific amount of energy.
Spectral Emission Lines: Distinct wavelengths (colors) of light emitted by an atom when its electrons transition to lower energy states.
