Vedclass · Answer

(D) Dalton's atomic theory was based on the laws of chemical combination.It successfully explained the $Law$ $of$ $conservation$ $of$ $mass$,the $Law$ $of$ $constant$ $composition$ (or definite proportions),and the $Law$ $of$ $multiple$ $proportions$.However,Dalton's theory did not explain the $Law$ $of$ $radioactivity$,as radioactivity involves the decay of atomic nuclei,which was not known at the time of Dalton.Therefore,the correct statements are $(i), (ii),$ and $(iv)$.

Dalton's atomic theory successfully explained:
$(i)$ Law of conservation of mass
$(ii)$ Law of constant composition
$(iii)$ Law of radioactivity
$(iv)$ Law of multiple proportions
