Assertion (A): Some alpha particles were seen to be deflected through small and large angles in the alpha particle scattering experiment.Reason (R): The atom contains a lot of empty space.

In Rutherford experiment a small fraction of  α -particles are scattered at small angle becauseSelect an answerA α  -particles are attracted by a negatively charged particleB α  -particles are pushed towards the heavy nuclear regionC α  -particles are repelled by positively charges regionD α  -particles are attracted by positively charged region

1.Rutherford’s ‘alpha (α) particles scattering experiment’resulted into discovery of(a) electron (b) proton (c) nucleus in the atom (d) atomic mass.

n an experiment, «-particles are allowed to strike a thin gold foil in a vacuum.Almost all the a-particles pass straight through the gold undeflected. Only a very small number of a-particles are deflected from their original path.This result reveals certain features of the atoms of the gold.State what is shown about atoms by the fact thatsome alpha particles deflected back the way they came

In Rutherford's experiment, the outcomes areA. By classical electrodynamics, the atoms will not be stable while radiating photonB. All incident alpha particles scattered only less than 5 degreesC. Electrons revolve around the nucleusD. There is a nucleus at the center

In the early part of the 20th century, experiments were carried out in which alphaparticles were directed at thin sheets of metal.A few alpha particles were deviated through small angles and a very small proportionwere reflected back.(a) The diagram represents an alpha particle reflected back through 180° as itapproached the nucleus of a gold atom.path of alpha particle nucleus ofgold atomCalculate the maximum acceleration of the alpha particle as it reaches the point ofminimum separation from the nucleus. Assume that the gold nucleus remains at rest.speed of alpha particle = 1.74 × 107 m s−1mass of alpha particle = 6.64 × 10−27 kgatomic number of gold = 79
