this image shows a stream of positively charged particles being directed at gold foil. the positively charged particles are called \alpha particles\ and each one is like a nucleus without any electrons. what is the best explanation for why a particle is striking point x? alpha particles are mostly empty space, so they move in random directions, and one of these alpha particles can strike point x. the gold atoms contain negative electrons, so when alpha particles strike the gold they keep moving but in various directions. if an alpha particle hits the gold foil, a gold nucleus splits and a particle from it flies out at point x. when the dense, positive alpha particle passes close to a positive nucleus of gold, the alpha particle repels and hits the screen at point x.
Answer
Brief Explanations:
Alpha particles are positively - charged. Gold nuclei are also positively - charged. According to the principle of like - charge repulsion in electrostatics, when a positively - charged alpha particle passes close to a positively - charged gold nucleus, it will be repelled and change its direction, which can cause it to hit point X.
Answer:
When the dense, positive alpha particle passes close to a positive nucleus of gold, the alpha particle repels and hits the screen at point X.
