Statement (A) As one considers orbits with higher values of n in hydrogen atom, the electric potential energy of the atom increases. Statement (B) In thomson's model, an atom is a spherical cloud of positive charges with electrons embedded in it. Statement (C) The orbital picture is Bohr's model of the hydrogen atom was consistent with the uncertainty principle.

Step-by-step solution

In hydrogen atom, potential energy of electron in n th orbit is given as PE = -K z e^2 r For higher value of n, r increase because r n^2 . From eq (i), it is clear that for higher value of n , potential energy increases. Hence, statement (A) is correct. In thomson's model an atom is a spherical cloud of positive charges with electrons embedded in it. Hence, statement (B) is correct. According to Bohr's model an electron in an atom is located at a definite distance from the nucleus and is revolving with a definite v
