Chemistry Topic 6 - Bohr's Model of the Atom

Front

What does the electromagnetic spectrum include?

Back

Many different types of radiation.

Front

What does E (quantum) represent in the equation E (quantum) = hv?

Back

The energy of a photon of light.

Front

Describe the electron orbits in ground and excited states around a proton.

Back

Electron orbits in ground state are closer to the proton.

Front

What color of light is emitted when an excited electron in the hydrogen atom falls from n = 4 to n = 2?

Back

Green.

Front

What is a characteristic of electromagnetic radiation?

Back

It travels in waves.

Front

Define the Bohr model of the atom.

Back

A model that describes electrons orbiting the nucleus in fixed paths or energy levels.

Front

What is the significance of the principal quantum number (n) in the Bohr model?

Back

It indicates the energy level of an electron in an atom.

Front

How does an electron transition from a higher energy level to a lower energy level in the Bohr model?

Back

By emitting a photon of light.

Front

What is the formula for calculating the energy of a photon?

Back

E = hv, where E is energy, h is Planck's constant, and v is frequency.

Front

What happens to the wavelength of light as the energy of the photon increases?

Back

The wavelength decreases.
