Question

The man destroyed of fill in the blanks​

Answer 1

Dalton’s atomic theory was able to explain the law of conservation of mass, law of constant

composition and law of multiple proportions very successfully. However, it failed to explain the results of

many experiments; for example, it was known that substances like glass or ebonite when rubbed with silk

or fur generate electricity. Many different kinds of sub-atomic particles were discovered in the twentieth

century. However, in this section we will talk about three particles, namely electron, proton and neutron.
