MCQ
Which statement about the Rutherford model of the atom is not true?
  • A
    There is a positively charged centre in an atom called the nucleus
  • B
    Nearly all the mass of an atom resides in the nucleus
  • ✓
    Size of the nucleus is comparable to the atom
  • D
    Electrons occupy the space surrounding the nucleus
✓

Answer

Correct option: C.
Size of the nucleus is comparable to the atom
c
(c)

In Rutherford model, positive charge acquires a very small place at centre of atom in nucleus.

So, option $(c)$ is incorrect.
