- 40) Going from the left to right in the periodic table, the size changes among the transition elements are more gradual than those among the representative elements. Select all that help explain why this is true. a) The electrons that are added from one element to another enter an outer (n – 1)d subshell. b) The outer electrons for the transition elements are in the ns orbital. c) The inner electrons for the transition elements are in the ns orbital. d) The electrons that are added from one element to another enter an inner (n – 1)d subshell.arrow_forwardExplain what is wrong with the given electron configuration.

- While boiling potatoes for dinner in salted water, the pot boils over and you notice that the flame on your gas burner turns to bright yellow-orange. How would you explain the appearance of a color in the previously blue flame?arrow_forwardAnalysis: What is an ion? Describe what happens to the electrons in an atom when they absorb energy (from the flame)? Why does this produce a bright-line emission spectrum (rather than a continuous spectrum)? In terms of atomic structure, why does each metal ion produce a different color flame? What difficulties are there in identifying metal ions with a flame test? How could you improve the specific identification of the metal ions during a flame test? If it can be determined from the flame test results, what are the identities of the two unknown liquids? What might be some practical (and exciting) applications of metal containing compounds that create different colors of light while burning? Explain.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
