Welcome back Philip — missed you this week. a) i) Light is quantized means that its energy is not continuous but exists in discrete packets called photons. Each photon carries a specific amount of energy. ii) The work function () is the minimum amount of energy required to remove an electron from the surface of a metal. iii) Step 1: Calculate the energy of the incident photon using the given frequency. E = hf E = (6.6 × 10^-34 J s) × (5.4 × 10^14 Hz) E = 3.564 × 10^-19 J Step 2: Use the photoelectric equation to find the work function (). E = + KE_max = E - KE_max = (3.564 × 10^-19 J) - (1.2 × 10^-19 J) = 2.364 × 10^-19 J Step 3: Calculate the minimum frequency (threshold frequency, f_0) using the work function. = hf_0 f_0 = ()/(h) f_0 = 2.364 × 10^-19 J6.6 × 10^-34 J s f_0 = 3.58 × 10^14 Hz The minimum frequency of radiation is 3.58 × 10^14 Hz. b) i) The atomic number (Z) is the number of protons found in the nucleus of an atom. It determines the element's identity. ii) The mass number (A) is the total number of protons and neutrons (nucleons) in the nucleus of an atom. c) i) The symbol for radon nuclide is _86^222Rn. ii) The decay process involves the emission of two beta particles (_-1^0). _86^222Rn _88^222Ra + 2 × _-1^0 The equation representing the decay process is _86^222Rn _88^222Ra + 2 × _-1^0. d) Three properties of x-rays are: • They are a form of electromagnetic radiation. • They travel at the speed of light in a vacuum. • They are not deflected by electric or magnetic fields.
