The de Broglie wavelength of an electron in the nth orbit of a hydrogen atom is proportional to (where n is the principal quantum number and Z = 1):
The work function of cesium is 2.14 eV. The threshold wavelength for cesium is: (h = 6.626 × 10⁻³⁴ J·s, c = 3 × 10⁸ m/s, 1 eV = 1.6 × 10⁻¹⁹ J)
The de Broglie wavelength of an electron moving with a velocity of 1.0 × 10⁶ m/s is: (h = 6.626 × 10⁻³⁴ J·s, mₑ = 9.1 × 10⁻³¹ kg)
Which of the following sets of quantum numbers is NOT allowed for an electron in an atom?
The uncertainty in the position of an electron moving with a velocity of 600 m/s is 0.001 nm. What is the uncertainty in its momentum? (h = 6.626 × 10⁻³⁴ J s)
The quantum numbers that describe the 3d orbital of an atom are:
The de Broglie wavelength associated with an electron accelerated through a potential difference of 100 V is approximately: (h = 6.626 × 10⁻³⁴ J·s, mₑ = 9.1 × 10⁻³¹ kg, e = 1.6 × 10⁻¹⁹ C)
