Solve this please please

Dear Student,

(i) Most of the space in an atom is empty, therefore, most of the alpha particles in Rutherford's experiment passed undeviated through the gold foil. 

(ii) According to Dalton's atomic theory, atoms of same element are alike but isotopes are the atoms of same element having different mass number, therefore, discovery of isotopes contradicted Dalton's atomic theory.

​​​​​​Kindly ask the remaining query in the next thread.

Regards,
