Given below are two statements :
$Statement$ $I$ : Most of the mass of the atom and all its positive charge are concentrated in a tiny nucleus and the electrons revolve around it, is Rutherford's model.
$Statement$ $II$ : An atom is a spherical cloud of positive charges with electrons embedded in it, is a special case of Rutherford's model.
In the light of the above statements, choose the most appropriate from the options given below.
Both statement $I$ and statement $II$ are false
Statement $I$ is false but statement $II$ is true
Statement $I$ is true but statement $II$ is false
Both statement $I$ and statement $II$ are true
Solution
According to Rutherford atomic model, most of mass of atom and all its positive charge is concentrated in tiny nucleus electron revolve around it.
According to Thomson atomic model, atom is spherical cloud of positive charge with electron embedded in it.
Hence,
Statement $I$ is true but statement $II$ false.
