1-ll Bonus THE ELECTRONIC STRUCTURE OF ATOMS 1. Indicate whether each of the following statements is trut or 8. Based on the relationship between electron configurations false a. An orbital bas a definite size and shape, which are related and the periodic table, indicate which elements cootain the electron characteristics below. In those cases wbere a series of elements have the indicated characteristics you beed not write all the symbols but rather may wrise the atoniic numbers of the first and last elements in the series, Le, elements 70-83 to the energy of the electrons it could contai.JL The M and n-3 shells are one and the same Allofthe orbtals in a subshell have the same energy.. d. c. All of the subshells in a shell have the same energy. a total of &2 e b. only three Sp electrons c. two 7s elecgpas (note that more than one electron c. A 2p and 3p subshell would contain the same number of orbitals. t A d subshell always contains five orbitals. se E An s orbital is shaped soenething like a fou-leaf clover. h The n-3 shell can accommodate a maximum of 18 electrons (they are not all in the a total of fifteen" tame sabshell) only one electronin shell atotal of six electrons (note that more than one element qualfies) c. i The fourth shell is made up of six subshells. . All subshells accommodate the same number of electrons 2 Give the maximum number of electrons that may occupy each 9. Referring oaly to the periodic table, determine de ofthe following units a 2p subshellb 2p orbital 6 c. third shell i d L shell 8 element of lowest asomic number whose electron d. a two complesely filled d subshells b. four completly filled s subabelsa c. four complesely filled s orbitas d. fur completely filled P orbitals e 4fshell 4foebital 2 3. For each of the Solowing sets of sebshells determine the one of lowest energy and the one of highest energy.p 151p 555p(A53d two com pleerly filled shell. four complenely falled shells four completely filled subshells three completely filed orbitals With the help of an Autbau diagra, write the complete electron configuration Sfor each of the following atoms h 4 10. Refering only to the periodic table, determine the element of lowest atomic number whose electron configuration conains the following a. more p electrons than s electrons b. more delectrons than p electrons c more f electrons than s electrons d. more d elections than electrons Give the reason why each of the following sets of quanoum rumbers is an impessibility 5.
