During a temperature test, Sample A conducts less well as temperature rises, while Sample B conducts better as temperature rises. Which conclusion is most consistent with typical metallic behavior?
A
Sample B is more likely metallic because metals conduct only after heating creates ions.
B
Sample A is more likely metallic because increased lattice vibrations scatter its mobile electrons.
C
Neither sample can contain electrons because conductivity changes with temperature.
D
Sample A must be ionic because solid ions become more fixed at high temperature.
