What is de Broglie’s hypothesis regarding electrons?
Electrons have wave-like properties and are associated with matter waves.
What does the amplitude of a wave relate to?
The amplitude is related to the presence of the wave in space and time.
According to de Broglie’s hypothesis, the circumference of a circular orbit should be equal to _______.
an integral multiple of the wavelength of the matter wave associated with the electron.
What is the relationship between angular momentum and wave characteristics of electrons?
The angular momentum of electrons is quantized and is an integral multiple of h.
What mathematical expression is derived from de Broglie’s hypothesis?
d = h / (m * v)
True or False: Bohr’s condition for the quantization of angular momentum is related to de Broglie’s wave idea.
True
What is the significance of the number of de Broglie wavelengths in an orbit?
It determines how many wavelengths fit into the circumference of Bohr’s stationary orbit.
Fill in the blank: The angular momentum is quantized and expressed as _______.
n * h / (2π)
What does the term ‘matter waves’ refer to?
Waves associated with particles, such as electrons, exhibiting wave-particle duality.
What is the key concept behind Bohr’s model of the atom?
Electrons occupy stationary orbits with quantized angular momentum.
