● Transition elements have variable oxidation numbers, form complex ions with ligands, have
coloured compounds, and display catalytic and magnetic properties.
Guidance
Common oxidation numbers of the transition metal ions are listed in the IB Data booklet in sections 9
and 14.
● Zn is not considered to be a transition element as it does not form ions with incomplete
d orbitals.
● Transition elements show an oxidation number of +2 when the s electrons are removed.

● Explanation of the ability of transition metals to form variable oxidation states from successive
ionization energies.
● Explanation of the nature of the coordinate bond within a complex ion.
● Deduction of the total charge given the formula of the ion and ligands present.
● Explanation of the magnetic properties in transition metals in terms of unpaired electrons.

Task:

1. Watch the video on the left (if you want to watch more please also have a look a the video on the right)
2. Use the knowledge from the video,  pearson  text book  page (120-121) , as well as the internet to research about the chemical and physical properties of transition metals 
3. Record your findings in the wakelet below - be sure to add images and diagrams as well 

Task:

1. Watch the videos and take notes 
2. Create a mindmap either electronically or on a poster about everything you have learned so far about transition metals including the properties discussed in the video 
3. Upload your mind map below
