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

What were the conclusions of the gold foil experiment?Group of answer choicesgold atoms are mostly empty spacegold atoms do not existgold atoms have a dense nucleus at their centregold atoms do not have a nucleusgold atoms are very strong

Rutherford expected alpha particle to travel almost straight through a target of gold foil. The results of his gold foil experiment did not supportGroup of answer choicesThomson’s plum pudding theoryMillikan’s oil drop experimentThe cathode ray phenomenonBohr’s atomic model

Ernest Rutherford fired α-radiation at an incredibly thin sheet of gold foil. Not all particles went through the gold foil. Some were deflected, and some bounced right back.Recall what this meant for the structure of the atom. Atoms are mostly empty spaces with a tiny charged nucleus orbited by electrons.1Atoms are solid with no empty space.2Atoms are made up of a positive matrix with negative electrons mixed in.3Atoms have a very large charged nucleus.

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 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.
