Transition Metals Flashcards
1
Q
Define a transition metal
A
Elements that form one or more stable ions which have partially formed d orbitals
2
Q
What order are 4s and 3d orbitals filled and emptied
A
4s filled first and emptied first
3
Q
Why are transition metals coloured?
A
Partially filled d orbitals. When ligands coordinate bond they cause d orbitals to split into two energy level. Frequencies of light excite electrons from one to the other.
