Properties of transition metals?
Good conductors of heat and electricity. Hard, strong, high mpt, high bpt, low chemical reactivity.
1 of 5
Electron configuration pattern?
Two outer 4s electrons, then moving across period e- are added to inner 3d sub-level. Cr and Cu are exceptions. Cr has 3d(5)4s(1) and Cu has 3d(10)4s(1), because half full and full subshells increase stability.
2 of 5
Which electrons are lost first?
4s, as they are of the highest energy.
3 of 5
Define Transition Element
Element that forms at least one stable ion with a partially filled d-sub shell.
4 of 5
Chemical properties of transition metals? (4)
Variable oxidation states, formation of coloured ions, catalytic properties, complex formation

this is a really bad resource, its not even very useful, if you are going to post stuff please make it better.
