A model of the atom which explained the atomic emission spectrum of hydrogen was proposed by Neils Bohr. Bohr suggested that an atomic spectrum is created when the electrons in an atom move between energy levels. In Bohr’s model, electrons exist in orbits around the nucleus which only exist at fixed distances from the nucleus called energy levels. According to the Bohr model electrons can orbit at many fixed distances from the nucleus. Bohr proposed electrons orbit at fixed distances from the nucleus in stationary states, such as the ground state or excited state to explain why they did not radiate energy while orbiting the nucleus

Use this to guide you- A model of the atom which explained the atomic emission spectrum of hydrogen was proposed by Neils Bohr.

**Text Transcription:**

"USE EVIDENCE and as many Word Wall words as you can to explain what is incorrect about the Bohr models drawn as it pertains to how atomic size changes with an element's position on the periodic table."

**Image Description:**

The image includes a diagram with what looks like a misunderstood Bohr model representation. There is a periodic table highlighted with colors:

- **Vertical Axis:** Labeled as "PERIOD."
- **Horizontal Axis:** Labeled as "GROUP."
- Colored sections represent different elements or groups on the periodic table.
- An illustration of an atom is present with electrons shown orbiting around a central nucleus.
- There is a directional arrow pointing right, indicating an increase or change correlated with the periodic table.

Handwritten text next to the diagram says "Look," directing attention to the specific aspects being discussed. The diagram aims to highlight misconceptions regarding how atomic size changes across periods and groups.
