In 1911, the alpha particle scattering experiment conducted by Rutherford's team led to a paradigm shift in our understanding of atomic structure.
Identify three conclusions about the structure of the atom that were deduced directly from the observations made during this experiment.
Explain why the previous "plum pudding" model of the atom had to be discarded in light of these new experimental findings.
An airtight laboratory chamber contains nitrogen gas. A diagram of the chamber is shown below.
Calculate the volume of the laboratory chamber.
Volume = ........................... m3\text{m}^3m3
The density of the nitrogen gas inside the chamber is 1.15 kg/m3. Calculate the mass of the nitrogen gas in the chamber.
Use the equation: density=massvolume\displaystyle \text{density} = \frac{\text{mass}}{\text{volume}}density=volumemass
Mass = ........................... kg\text{kg}kg
