in my book it says that 'sometimes a particle is deflected through nearly 180*' after it hits the gold leaf. why does it say NEARLY 180*? surely it should be 180* full stop lol.

I think it is fully 180 degrees if it hit the gold foil nuclei.
It is nearly 180 degrees if it gets repelled by the positive charge I think.
I watched this video and it’s really helpful

I'm a perfect experiment, the deflection would indeed be 180. The 'sometimes and nearly' parts are the result of experimental inaccuracy caused by (amongst other things) the random vibration positions of the targets atomic structure and the finite probability of all incident particles hitting every target precisely. Ergo they never will and hence scatter to produce a less than perfect 180 degree answer.
