Vedclass · Answer

(A) Thomson proposed that an atom consists of a positively charged sphere with electrons embedded in it,similar to seeds in a watermelon or plums in a pudding.Therefore,the statement $A$ is true because it is historically called the plum pudding model.Statement $R$ correctly describes the structure of this model,which serves as the basis for the name given in statement $A$.Thus,$A$ and $R$ are both true and $R$ is the correct explanation of $A$.

$A$: Thomson's atomic model is known as the plum pudding model.
$R$: The atom is considered as a positively charged sphere in which electrons are embedded.
