Passage VI
An atom has a nucleus, which consists of protons (positively charged particles) and neutrons (uncharged particles), surrounded by one or more electrons (negatively charged particles) which move in orbits (see Figure 1).
Table 1 contains data for several neutral and charged atoms containing only one electron. Table 1 includes the number of protons (Z); the identification of the initial orbit (n); the radius of the orbit (r); the energy (l, in electron volts, or eV) to remove an electron from the atom; and the energy (E) of a photon emitted when an electron falls from its initial orbit to the orbit where n = 1.
35. The most energetic photons will be emitted when an electron falls from orbit:
Your Answer is
Correct Answer is D
Explanation
See E in table 1 (the energy of a photon emitted when an electron falls from its35. See E in table 1 (the energy of a photon emitted when an electron falls from its initial orbit to the orbit where n= 1), B+3 and n=4 corresponds to the largest E
