Question

Why is it hard to test the particle model to see if it is correct?

Answer 1

Please refer to the explanation below.

Explanation:

I would say that it is because particles are extremely, extremely tiny! If we say that a particle is an atom, it is roughly `0.3nm=3*10^-10m` in diameter. That's really hard to imagine, let alone see!

To do that, we would have to use something called electron microscopes. Those are microscopes, but they are very powerful, and are able to see electrons and other particles. The downside is that they are hard to operate, and are very expensive to buy.

In conclusion, I would say that those are the two main reasons of why it is hard to test the particle model.
