What is Bohr's Model of the Atom?

Back

A model that describes the atom as having quantized energy levels where electrons orbit the nucleus in defined paths.

Front

What happens when an electron falls from a higher energy level to a lower one in the Bohr model?

Back

A photon of light is emitted, corresponding to the energy difference between the two levels.

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 the purpose of a flame test in chemistry?

Back

To identify the presence of specific metal ions based on the color of light emitted.

Front

Which of the following is NOT a characteristic of waves?

Back

Density.

Front

What symbol is used to represent wavelength in wave characteristics?

Back

λ (lambda).

Front

What is the relationship between wavelength and frequency?

Back

They are inversely related; as wavelength increases, frequency decreases.

Front

What is quantization in the context of atomic energy levels?

Back

The concept that electrons can only exist in specific energy levels, not in between.

Front

What is the significance of the hydrogen spectrum in understanding atomic structure?

Back

It provides evidence for quantized energy levels and the transitions of electrons.

Front

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

Back

E = hν, where E is energy, h is Planck's constant, and ν is frequency.
