  Which of the following in figure do not represent Bohr's model of an atom correctly? (a) (i) and (ii)                      (b) (ii) and (iii)                    (c) (ii) and (iv)                    (d) (i) and (iv)

Answer:

  (c) Figures (ii) and (iv) not correctly represent the Bohr's model of an atom. It is because maximum number of electrons in (I) shell is 2, not 4, so (ii) is wrong and maximum capacity of L (II) shell is 8 electrons, not  9. So, (iv) is also 'wrong.
