Final answer:
To calculate the de Broglie wavelength of an atom, use the equation λ = h / (mv), where h is Planck's constant, m is the mass of the atom, and v is the velocity.
Step-by-step explanation:
The de Broglie wavelength of an object can be calculated using the equation:
λ = h / (mv)
where λ is the de Broglie wavelength, h is Planck's constant (6.626 x 10-34 J·s), m is the mass of the object, and v is the velocity of the object.
To calculate the de Broglie wavelength of an atom, you need to know its mass and velocity. The mass of the atom can be obtained from the periodic table, and the velocity can be given in units of meters per second (m/s).
Plug in the values into the equation to find the de Broglie wavelength in meters.
