Transition Metals
- There is only one liquid transition metal at room temperature. It is Mercury (Hg). All the others elements in the transition metals are solid.
- The transition metals are the subgroups between groups IIA and III A.
- The transition metals are classified differently due to the filling of their d sub shell orbital.
- All transition metals are metallic and have high electrical conductivity.
- They are called "transition metals" because they are metallic elements that serve as a bridge, or transition, between the two sides of the periodic table.
-Transition metals are the only elements that can produce a magnetic field.
