(a) Name and state the principle, which restricts the maximum number of electrons in an orbital to be two.
(b) Using s, p, d, f notation represent the sub-shell with the following quantum numbers.
(i) n = 1, l = 0
(ii) n = 4, l = 3
(c) The uncertainty in the position and velocity of a particle are 10 cm and 5.27 × 103 m/s respectively. Calculate the mass of the particle (h=6.626 × 10-34 J s).
