Document Summary

Transition metals and coordinating compounds: many biological molecules contain transition elements in arrangements. Properties of transition metals: almost all transition metals have moderate to high densities, good gemstones. 24. 2) electrical conductivity, high melting points, and moderate to extreme hardness (properties similar to main group elements because of similar electron configurations: have electrons in d orbitals that can be involved in metallic bonding) 6, [co(nh3)6]3+ as a complex ion and three cl- counterions, cl- can replace nh3 in the secondary valence (cl- can either act as a counterion or bond directly to the metal part of the complex ion) 4: square planar or transition metals tetrahedral depending on the number of d electrons in the metal ion (d8. 6: octahedral: name of cation goes before anion (as with all salts) H2o aqua; nh3 ammine; co carbonyl); name anionic ligands with the name of the ion plus an ending (-ide -o; -ate ato; -ite ito)
