What is the minimum uncertainty in the velocity of an electron that is known to be somewhere between 0.05 nm and 0.1 nm from the proton? 12. An electron travels with a speed of 3.60560 ± 0.00021 m.s1 . What is the minimum uncertainty in its position? 13. Find the energy required to excite a hydrogen electron from (i) the ground state to n = 3, (ii) from n = 2 to n = 3 14. What is the frequency of light that would excite the electron of a hydrogen atom from (i) n = 2 to n = 5, (ii) n = 2 to n = ∞ 15.
