Question

1. what properties did rutherford use in the design of the gold foil experiment?

o alpha particles positive charge and electrons negative charge
o alpha particles negative charge and gold foils positive charge
o alpha particles negative charge and random distribution of protons
o positively charged electrons distributed in a uniform negative charge

Explanation:

Rutherford knew alpha - particles are positively charged. He used this property along with the fact that electrons have a negative charge to design the experiment. The interaction between the positively - charged alpha particles and the negatively - charged electrons (and the overall structure of the atom) was of interest. The other options have incorrect charge assignments for alpha particles or incorrect models of atomic structure.

Answer:

alpha particle's positive charge and electron's negative charge
