Question

In the Gold foil experiment of Geiger and Marsden which paved the way for Rutherfords model of an atom 100 of the particles were found to deflect at angles 50 If one mole of particles were bombarded on the gold foil compute the number of particles that would deflect at angles less than 500

Accepted Answer

Total number of particles used for bombardment 1 mole 1 mole60221023 particle number of particles deflected at angles greater than 5050 1 Number of particles deflected at angles greater than 50 1001 99 The actual number of particles deflected at angles less than 50 99100 6022 1023 596 1023
