- Fluoride ion, F, has no unpaired electrons. Vanadium forms four binary fluoridesVF2, VF3, VF4, and VF5. Assume that all four are ionic compounds. (a) Which fluoride is diamagnetic? (b) Which fluoride has the greatest attraction to a magnetic field? (c) Which fluoride has two unpaired electrons per vanadium?arrow_forwardWrite the ground state electron configuration for (a) Mg, Mg2+(b) N, N3- (c) Ti, Ti4+ (d) Sn2+ Sn4+arrow_forwardThese questions are not designated as to type or location in the chapter. They may combine several concepts. The red color of rubies is the result of the substitution of some Cr3+ ions for Al3+ ions in solid Al2O3. (a) Using spdf notation with the noble gas notation, write the electron configuration for the Cr atom and for the Cr3+ ion? (b) Is Cr2+ paramagnetic? Is Cr3+? (c) The radius of the Cr3+ ion is 64 pm. How does this compare with the radius of the Al3+ ion?arrow_forward
- The electron affinity of the lutetium atom (element 71) was measured using the technique of photoelectron spectroscopy with an infrared laser (the essay on p. 310 describes this instrumental method, using X rays). In this experiment, a beam of lutetium negative ions, Lu, was prepared and irradiated with a laser beam having a wavelength at 1064 nm. The energy supplied by a photon in this laser beam removes an electron from a negative ion, leaving the neutral atom. The energy needed to remove the electron from the negative ion to give the neutral atom (both in their ground states) is the electron affinity of lutetium. Any excess energy of the photon shows up as kinetic energy of the emitted electron. If the emitted electron in this experiment has a kinetic energy of 0.825 eV, what is the electron affinity of lutetium?arrow_forwardTitanium metal and Cr2+ have the same number of electrons. However, the electron configuration of Ti is [Ar] 4s23d2, but that of Cr2+ is [Ar] 3d4. Explain.arrow_forwardAnswer the questions below concerning ground state electron configurations. (a) What element has the electron configuration [Ar]3d64s2? (b) What element has a 2+ ion with the configuration [Ar]3d5? Is the ion paramagnetic or diamagnetic? (c) Mow many unpaired electrons are in a Ni2+ ion? (d) The configuration for an element is given here. What is the identity of the element? Is a sample of the element paramagnetic or diamagnetic? How many unpaired electrons does a 3 ion of this element have? (e) What element has the following electron configuration? Write a complete set of quantum numbers for electrons 1-3.arrow_forward
