when Rutherfort Alfa scattering experiment occurs Alfa partical enter the gold foil then why don't the positive Alfa particle react with the electron and become nutral

Question

Answer

I checked in Quora and this was the answer given:'In some versions of the experiment, the alpha particle beam was fired though a vacuum so there were no electrons to attract. But even if not in a vacuum, the alpha particles are initially flying too fast to attract electrons. Of course, as they lose energy, they slow, and they quite soon will attract electrons. But late enough for the experiment to be performed.'

Answer

becoz that alpha particles were going with very very high speed might be.
