- The electron of a hydrogen atom is excited to the 4d orbital. Calculate the energy of the emitted photon if the electron were to move to each of the following orbitals: (a) 1s; (b) 2p; (c) 2s; (d) 4s. (e) Suppose the outermost electron of a potassium atom were excited to a 4d orbital and then moved to each of these same orbitals. Describe qualitatively the differences that would be found between the emission spectra of potassium and hydrogen (do not perform calculations). Explain your answer.arrow_forwardImagine a four-dimensional world. In it, atoms would have one s orbital and four p orbitals in a given shell. (a) Describe the shape of the Periodic Table of the first 24 elements. (b) What elements would be the first two noble gases (use the names from our world that correspond to the atomic numbers).arrow_forwardThe electron affinity of thulium was measured by a technique called laser photodetachment electron spectroscopy. In this technique, a gaseous beam of anions of an element is bombarded with photons from a laser. The photons knock electrons off some of the anions, and the energies of the emitted electrons are detected. The incident radiation had a wavelength of 1064 nm, and the emitted electrons had an energy of 0.137 eV. Although the analysis is more complicated, we can obtain an estimate of the electron affinity from the energy difference between the photons and the emitted electrons. What is the electron affinity of thulium in electron volts and in kilojoules per mole?arrow_forward

Part 1: How many different compounds are formed in this process? 1 Part 2 out of 2 Draw the product of the reaction. draw structure ...arrow_forwardMany fireworks use magnesium to burn, which releases a significant amount of energy. The heat released causes the oxide to glow, emitting white light. The color of this light can be changed by including nitrates and chlorides of elements that emit in the visible region of their spectra. One such compound is barium nitrate, which produces a yellow-green light. Excited barium ions generate light with wavelengths of 487 nm, 524 nm, 543 nm, and 578 nm. For each case, calculate: (a) the change in energy (in electron volts) of a barium atom and (b) the molar change in energy (in kilojoules per second).arrow_forwardClouds of hot, luminous interstellar hydrogen gas can be seen in some parts of the galaxy. In some hydrogen atoms, electrons are excited to quantum levels with n = 100 or higher. (a) Calculate the wavelength observed on Earth if the electrons fall from the level with n = 100 to one with n = 2. (b) In what series would this transition be found? (c) Some of these high-energy electrons fall into intermediate states, such as n = 90. Would the wavelengths of a transition from the state with n = 100 to one with n = 90 be longer or shorter than those in the Balmer series? Explain your answer.arrow_forward
- In the spectroscopic technique known as photoelectron spectroscopy (PES), ultraviolet radiation is directed at an atom or molecule. Electrons are ejected from the valence shell and their kinetic energies are measured. Since the energy of the incident ultraviolet photons is known and the kinetic energy of the ejected electron is measured, the ionization energy, I, can be deduced because total energy is conserved. (a) Show that the velocity, v, of the ejected electron and the frequency, n, of the incident radiation are related by hv = I + (1/2)mv^2? (b) Use this relation to calculate the ionization energy of a rubidium atom, knowing that light of wavelength 58.4 nm produces electrons with a velocity of 2,450 km/s Recall that 1 J = 1 kg.m^2/s^2arrow_forwardI) In Millikan's experiment, each droplet observed by the technicians contained an even number of electrons. If they had been unaware of this limitation, how would it have affected their report of an electron's charge?II) Millikan measured the charge of an electron in electrostatic units, esu.
