19.1 Occurrence, Preparation, and Properties of Transition …

Transition metals can form compounds with a wide range of oxidation states. Some of the observed oxidation states of the elements of the first transition series are shown in Figure 3 . As we move from left to right across the first transition series, we see that the nuer of common oxidation states increases at first to a maximum towards the middle of the table, then decreases.

2015/4/24· So the oxidation nuer of Mn in MnO is +2, and the name of the compound is manganese(II) oxide. The oxidation nuer of Mn in MnO₂ is +4, and the name of the compound is manganese(IV) oxide. The most common ions with multiple oxidation nuers are

5.2 Naming Binary Compounds That Contain a Metal and …

For example, lead (Pb) can form Pb2+ or Pb4+ in ionic compounds. Also, iron (Fe) can produce Fe2+ or Fe3+, chromium (Cr) can produce Cr2+ or Cr3+, gold (Au) can produce Au+ or Au3+, and so on. This means that if we saw the name gold chloride, we wouldn’t know whether it referred to the compound AuCl (containing Auﰀ and Clﰁ) or the compound AuCl3 (con- taining Au3+ and three Cl- ions).

Why are nitrate and chloride compounds used in the …

2012/3/19· I was doing a science lab, commonly known as the ''flame test'' In the lab we tested different compounds such as calcium chloride. One of the analysis questions asks why we had to use compounds for the lab. At first I had no idea because to me it made sense to just burn the metals themselves and see what colour the flames were (as that is what the lab is interested in) but doing …

Covalent Compounds | …

Ionic compounds tend to be brittle in their solid form and have very high melting temperatures. Covalent compounds tend to be soft, and have relatively low melting and boiling points. Water, a liquid composed of covalently bonded molecules, can also be used as a test substance for other ionic and covalently compounds.
