Definition Definition Elements containing partially filled d-subshell in their ground state configuration. Elements in the d-block of the periodic table receive the last or valence electron in the d-orbital. The groups from IIIB to VIIIB and IB to IIB comprise the d-block elements.
Chapter 7, Problem 22E
(i)
Interpretation Introduction
To determine: The authenticity of the statement, “For a given period, the radii of the representative elements generally decrease from left to right across period.”
(ii)
Interpretation Introduction
To determine: The authenticity of the statement’ “The radii of the representative elements for the n=3 period are all larger than those of the corresponding elements in the n=2 period.”
(iii)
Interpretation Introduction
To determine: The authenticity of the statement, “For most of the representative elements, the change in radius from the n=2 to the n=3 period is greater than the change in radius from n=3 to n=4 .”
(iv)
Interpretation Introduction
To determine: The authenticity of the statement, “The radii of the transition elements generally increase moving from left to right within a period.
(v)
Interpretation Introduction
To determine: The authenticity of the statement, “The large radii of the Group 1A elements are due to their relatively small effective nuclear charges.”
