Question

To daw the geometrical representation for the structure of the oxygen atom the following steps are given. Identify the correct sequence of the steps. I) The eight electrons present in the extranuclear part would be distributed in the first two orbits, i.e., K and L. As per the rules, two electrons would occupy the K-orbit and the remaining six electrons occupy the L-orbit. II) The atomic number of oxygen is 8. III) In the nucleus, 8 protons and 8 neutrons are present and in the extranculear part, i.e., in the orbits, 8 electrons are present. IV) Oxygen atom has 8 electrons and 8 protons. The mass number is 16, and hence, the number of neutrons is equal to 16 8 8   O  . A) II, I, III, IV B) III, I, IV, II C) II, IV, III, I D) III, IV, II, I
