cobalt Rhodium Iridium Meitnerium

1. Can you see any trends in the information collected?? yes I can see how they are in the same family trasition metal but have different information such as the melting point that vary different degrees 2. How are the elements of this family the same?? because they all relate to metal and metallic 3. How are the elements of this family different?? because all element have the same things it its just that have different atomic, atomic mass, protons, valence,no. of shell, melting point, atomic radium.

Tends: the appearences turns to dark and goes lighter until coloured for each elements and for the atomic, atomic mass and of shells goes increasing. and for atomic radium and melting is decreasing.

Uses of these elements and/or their compounds.
 * [|Cobalt(II) cyanide]- It is used as a catalyst
 * [|Cobalt(II) fluoride] - used as a catalyst to alloy metals.
 * [|Cobalt(II) naphthenate] - NA


 * [|Cobalt(II) nitrate] - metal organic frameworks and coordination chemistry.
 * [|Cobalt(II) oxalate] -N / A
