Statement -1 : Large angle scattering of alpha particles led to the discovery of atomic nucleus.
Statement -2 : Entire positive charge of atom is concentrated in the central core.

(A) Large angle of Scattering of alpha particles led to the discovery of atomic nucleus (R) : Entire positive charge of atom in concentrated in the central core .

General instructions same as in chapter 1. Assertion:Large angle scattering of alpha particle led to the discovery of atomic nucleus. Reason:Entire positive charge of atom is concentrated in the central core.

Large angle scattering of alpha- particle led Rutherford to the discovery of atomic nucleus. It is the tiny central core of every atom in which entire positive charge of the atom is concentrated. The distance of closet approach of alpha particle from the nucleus is r_(theta)=((Ze)(2e))/(4pi epsilon_(theta)((1)/(2)mv^(2))) This distance r_(theta) gave him the order of size of nucleus. Read the above passage and answer the followign question: (i) What is the distance of closet approach of an alpha particle of energy 7.7 MeV from gold nucleus (z=79)? (ii) What is the implication of this relation in day to day life?

The entire mass and positive charge of an atom is concentrated into its............

A: a-particles with a large angle scattered leads to the discovery of the nucleus of the atom. R: The central part of the atom is almost concentrated by positive electric charges

In Rutherford atomic model central part of atom where whole positive charge of atom is concentrated is called ......

The reason for Rutherford’s conception that the whole of positive charge in an atom is concentrated in the nucleus is

For scattering of alpha -particles at large angles, only the nucleus of the atom is responsible, explain why?

Statement -I : When projected to words towards as atoms having heavy nucleus , most of the alpha particle will pass through it without appereciable decviation. ltbr. Statement -II : All the positive charge of atom is located in a small dense located at center.
