I need help with 7.144 7.99 What are the condensed electron configurations of the following ground-state atoms andions? How many unpaired electrons are there in each?(а) К(b) K*(c) S²-(d) N(е) Ва(f) Ti**(g) Al7.140 Interstellar Hydrogen Astronomers have detected hydrogen atoms in interstellar spacein the n = 732 excited state. Suppose an atom in this excited state undergoes a transitionfrom n = 732 to n= 731.a. How much energy does the atom lose because of this transition?b. What is the wavelength of radiation corresponding to this transition?c. What kind of telescope would astronomers need to detect radiation of this wavelength?(Hint: It would not be one designed to capture visible light.)7.144 A green flame is observed when copper(II) chloride is heated in aflame (Figure P7.144).a.
