Assertion: The number of Electrons in the valence shell of helium atom is 2.Reason: The valency of helium is 2.12. Assertion: Protium and deuterium are isotopes.Reason: Isotopes have same mass numbers.13. Assertion: Atom is electrically neutral.Reason: A neutral particle, neutron is present in the nucleus of atom.14. Assertion: Cathode Rays get deflected towards the positive plate of electricfield.Reason: Cathode rays consist of negatively charged particles, known as electrons.15. Assertion: In Rutherford’s experiments, some of 𝛼-particles deflect by largeangles.Reason: 𝛼-particles are much heavier than the protons
