Buttler 1a. representative elements = elements in the A groups of the periodic table b. d -transition elements = elements in the B groups of the periodic table with partially filled d orbitals c. inner transition elements = metals where the f orbitals are being filled 9. Identify the elements and the part of the periodic table in which the elements with the following configurations are found. a. calcium, alkaline earth metals b. neon, noble gases c. calcium, alkaline earth metals d. sodium, alkali metals e. chlorine, halogens f. rhodium, transition metals 12. the electrons closest to the nucleus shield the outer electrons from the nuclear charge; it makes the atomic radii larger 14. it’s somewhere around two angstroms 18a. first ionization energy = energy it takes to remove the loosest electron from a

Unformatted text preview: gaseous atom b. second ionization energy = energy it takes to remove the second loosest electron from a gaseous atom 19. because the second electron is now part of a cation as opposed to a neutral atom 35. hydrogen ions are smaller than hydrogen atoms, chloride ions are larger than chlorine atoms, oxide ions are larger than oxygen atoms 41. electronegativity is where an atom in a molecule has electrons more attracted to it than to the other atom 42. Arrange the members of each of the following sets of elements in order of increasing electronegativities: a. Pb < Sn < Ge < C b. Na < Mg < S < Cl c. Bi < Sb < P < N d. Ba < Sc < Si < Se < F...
