Block metal chemistry the first row metals

Occurrence, extraction and uses Physical properties Inorganic chemistry 

The chemistry of the first row -block metals is best considered separately from that of the second and third row metals for several reasons, including the following  

The emphasis of this chapter is on inorganic and coordination chemistry organometallic complexes are discussed in Chapter 24. 

The major ore of chromium is chromite (FeCr204) which has a normal spinel structure (see Box 13.6 and Section 21.10). Chromite is reduced with carbon to produce 

Na2Cr04 and insoluble Fe203. Extraction with water followed by acidification with H2SO4 gives a solution from which Na2Cr207 can be crystallized. Equations 22.2 and 22.3 show the final two stages of production.
