Assign each element in the first row of the transition metals, scandium through zinc, to a group member. Have each group member look up on the Internet or in a reputable chemistry reference book the electrical resistivity for his or her element(s).

Agree on the units and temperature. As a group, prepare a graph of resistivity versus atomic number. What is the general trend in resistivity as the atomic number increases? What atomic properties might account for this trend? Are there any notable exceptions?
