Document Summary

You can pick your exam from my office (chemistry. Unit 3 transition metals & coordination chemistry. Periodic table similar properties occur down a vertical group. So in adding a d e , the chemistry is not affected much by adding one or even several core e . Most transition metals (tm) can absorb visible light. Many compounds are paramagnetic (unpaired e ), that is they are attracted by a magnet. Au, pt oxide layer protects surface oxide forms but surface corrodes no oxide forms. Can lose all their 4s and 3d e . So maximum oxidation state of mn can be +7 (mno4. Beware, they don"t have to lose all electrons. [noble gas] n s2 (n 1) dx x = 1 10 n s energy level is slightly lower than (n 1) d. 4s e are removed before the 3d e . Coordination compound = complex ion(s) + counter ion(s) that form together a neutral compound.
