Question

1 CO& molecules. Justify your answer. rst ionization energies for Na and K are given in the table below. Na metal reacts vigorously with water to form hydrogen gas and a metal hydroxide. K metal reacts vigorously as well, but it bursts into a violet-colored flame Element First Ionization Energy (J/mol) Na 4.95 x 105 4.19 x 10s Based on principles of atomic structure, explain why the first ionization energy of K is lower than the first A student hypothesizes that the flame is violet colored because violet light consists of photons that have Calculate the energy, in J, of one photon of violet light with a wavelength of 423 nm. a. Write the electron configuration for a K ion. b. ionization energy of Na. c. the energy needed to ionize K atoms. The wavelength of the violet light is measured to be 423 nm. i. ii. Is the energy of one photon of the violet light sufficient to cause the ionization of a K atom? Justify your answer.
