Book Free DemoIn the gold foil experiment of Geiger and Marsden, which paved the way for Rutherford’s model of an atom, ~ \(1.00\)% of the α-particles were found to deflect at angles > \(50\)°. If one mole of alpha particles were bombarded on the gold foil, compute the number of alpha particles that would deflect at angles less than \(50\)°.
Percentage of alpha particles deflected more than \(50\)° \(=\) \(1\)%
Percentage of alpha particles deflected less than \(50\)° \(=\) \(100 -1\) \(=\) \(99\)%
Number of alpha particles bombarded \(=\) \(1\) mole \(=\) \(6.022\times10^{23}\) particles
Number of particles that deflected at an angle less than \(50\)°
\(=\) \(\frac{99}{100}\times6.022\times10^{23}\)
\(=\)
