WebDetailed Solution for Assertion & Reason Test: Atoms - Question 1 According to Rutherford, “the entire positive charge and most of the mass of the atom is concentrated in a small volume called the nucleus, with electrons revolving around the nucleus just as planets revolve around the Sun.”. So the assertion is false. WebAssertion: The specific charge of anode ray particles depends on nature of the gas taken in the discharge tube. Reason: The particles in anode rays carry positive charge. (a) Both assertion and reason are correct and reason is the correct explanation of assertion.
WebAssertion: Atoms are electrically neutral. They do not have net electrical charge. Reason: Number of protons and electrons are equal. Hence, total positive charges are balanced with total negative charges. Solve any question of Structure of Atom with:- Patterns of problems > Was this answer helpful? 0 0 Similar questions
