|
| Transition Metals |
Groups 3
through 12; metals which are less reactive than
groups 1 & 2 (except Mercury). The transition
metals are denser, harder and have higher melting
points than the elements in Groups 1 & 2.
There are often irregularities in electron
configurations (notably S subshell of highest
energy level). |
