Which experiment led to the nuclear model of the atom.
Geiger-Marsden experiment. It is also called the Rutherford (gold foil) experiment.
When do atoms emit light?
When the electrons fall from a “high” to a “low” energy level.
How can you excite electrons?
It is best for a gaseous sample. Heat the sample or apply a high potential difference.
How does the density of the nucleus vary on the periodic table?
How does the radius of the nucleus vary with mass number?
In nuclide notation, what does “A” represent?
In nuclide notation, what does “Z” represent?
What does an emission spectrum look like?
What does an absorption spectrum look like?
A photon has a wavelength of 340 nm. What is its energy, in Joules?
A photon has a wavelength of 340 nm. What is its energy, in eV?
A photon has a wavelength of 550 nm. What is its energy, in Joules?
A photon has a wavelength of 550 nm. What is its energy, in eV?
