What is the Q value for lead in the Rutherford Experiment?

[the whizz]

in a problem using the Rutherford scattering experiment, i Need to find what the turning distance would be using lead instead of gold. I have that gold has a Q= 79e, what would the Q = ?? for lead?

Gold has an atomic number of 79 - hence 79 protons in the nucleus. The charge is then 79e.

What do you think this would be for Lead? You might need a periodic table to help you with this one.

The Rutherford scattering experiment is a well-known experiment conducted by Ernest Rutherford in 1911 to study the structure of the atom. In this experiment, Rutherford used a thin gold foil and bombarded it with alpha particles. The aim was to determine the structure of the atom by observing the deflection of the alpha particles as they passed through the foil.

Now, in order to determine the turning distance using lead instead of gold, we need to first understand the concept of Q value. The Q value, also known as the atomic number, is the number of protons in the nucleus of an atom. In the case of gold, the Q value is 79, which means it has 79 protons in its nucleus.

In comparison, lead has a Q value of 82, which means it has 82 protons in its nucleus. This is because lead has three more protons than gold. Therefore, the Q value for lead would be 82e.

To determine the turning distance using lead, we can use the same formula used in the Rutherford scattering experiment:

R = k * Q * Z / b

Where:
R = turning distance
k = constant
Q = atomic number
Z = charge of the alpha particle
b = impact parameter

By substituting the values of k, Q, and Z for lead, we can calculate the turning distance for lead. However, it is important to note that the turning distance for lead would be slightly different from that of gold due to the difference in their atomic structures.

In conclusion, to find the turning distance using lead instead of gold, we need to calculate the Q value for lead, which is 82e, and then use the same formula as in the Rutherford scattering experiment to determine the turning distance. This experiment can provide valuable insights into the atomic structure of lead and help us understand its properties better.
