Which of the following statements about Rutherford's model of atom are correct? (i) considered the nucleus as positively charged (ii) established that the α-particles are four times as heavy as a hydrogen atom (iii) can be compared to solar system (iv) was in agreement with Thomson's model
Rutherford's 'alpha (α) particles scattering experiment' resulted in to discovery of
Why did Rutherford select a gold foil in his α–ray scattering experiment?
Fill in the blanks in the following statements (a) Rutherford's α-particle scattering experiment led to the discovery of the ——— (b) Isotopes have same ———but different———. (c) Neon and chlorine have atomic numbers 10 and 17 respectively. Their valencies will be———and———respectively. (d) The electronic configuration of silicon is ———and that of sulphur is ———.
Enlist the conclusions drawn by Rutherford from his α-ray scattering experiment.
In the Gold foil experiment of Geiger and Marsden, that paved the way for Rutherford's model of an atom, ~ 1.00% of the α-particles were found to deflect at angles > 50º. If one mole of α-particles were bombarded on the gold foil, compute the number of α-particles that would deflect at angles less than 50º.
