Gold, like iron, copper, lead and tin is a metal. Gold is the only yellow metal and is chemically very stable. It does not readily combine with other substances and, therefore, does not corrode or tarnish. Because of this property, it is almost always found in nature as pure gold. This is referred to as 'native gold'.

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is ...

Iron takes the sulphate away from copper. You see that a reaction takes place and copper is left by itself. Now, we can say that iron has displaced copper from copper sulphate. Copper sulphate + Iron——— Iron sulphate + Copper. In such a reaction, the more reactive metal displaces the less reactive metal. Thus, the above activity shows ...

Naming transition metal cations is also complicated by their ability ionize through multiple pathways. In Section 3.3, cations were named by including the word "ion" after the name of the element that was ionized. Therefore, the ion symbolized as "Fe +2 " should be named as an "iron ion." However, the ion symbolized as "Fe +3 " should also be ...
