1.	To draw the geometrical representation for the structure of the oxygen atom the following steps are given . Identify the correct sequence of steps. (a) The eight electrons present in the extra-nuclear part would be distributed in the first two orbits that is K and L. As per the rules , two electrons would occupy K orbit and the remaining six electrons occupy the L orbit. (b) The atomic number of oxygen is 8. ltbr. (c) In the nucleus , 8 protons and 8 neutrons and present and in the extra-nuclear part, that is in the orbits, 8 electrons are present. (d) Oxygen atom has 8 electrons and 8 protrons .

Answer» b a c d c a d b b d c a c d b a Solution :(i) The atomic number of oxygen is 8. (ii) Oxygen atom has 8 electrons and 8 protons . The mass number is 16, hence hte number of neutrons is equal to `8[""_(8)O^(16)]`. (iii) In the nucleus, 8 protons and 8 neutrons are PRESENT and in the extra-nuclear part that is in the orbits , 8 electrons are present .(iv) The EIGHT electrons present in extra nuclear part, would be distributed in first two orbits that is K and L . As per the RULES ,two electrons would OCCUPY K orbits and remaining six electrons in L-orbit.
