how many valence electrons in transition elements
« on: August 09, 2008, 08:48:33 PM »
VAlence electrons are defined as the electrons in the highest numbered shell which would mean that the valence ecltrons of Titanium are 4s2. However the electronic configuration of titatium is [Ar]3d24s2. Which are the valence electrons of titanium?

You can call it 2, or 4, or 2-4. Valence electrons are not the best things for transition metals.

You may find the following link helpful in explaining the role of the 3d electrons in transition metal bonding and also why transitions have variable oxidation states

http://www.chemguide.co.uk/inorganic/transition/features.html#top

I will be interested if you have any comments positive or negative on that article
