They have the lowest melting points among all transition metals.
Many compounds are known, especially for the early transition metals.
There are more transition metals than any other groups in the periodic table.
The transition metals in period 8 are expected to be element 156 to 164.
Chromium is a member of the transition metals, in group 6.
