Instructor: Catherine Drennan, Elizabeth Vogel Taylor. they are hard, good conductors of heat and electricity, and melt and evaporate at high temperatures. Transition metals can lose valence electrons and form cations They have simple hcp, ccp and bcc lattices characteristic of true metals. In octahedral complexes with between four and seven d electrons both high spin and low spin states are possible. This is because of the low energy gap between states. I was an ex-school teacher in Singapore teaching chemistry. While the term transition has no particular chemical significance, it is a convenient name by which to distinguish the similarity of the atomic structures and resulting properties of the elements so designated.
