Question

why ores are generally found as their oxides of sulphide and carbonate but not as nitrite and nitrate​

Answer 1

Answer:

The metals at the bottom of the activity series are the least reactive. They are often found in a free state. For example, gold, silver, platinum and copper are found in the free state. Copper and silver are also found in the combined state as their sulphide or oxide ores. The metals at the top of the activity series (K,Na,Ca,Mg and Al) are so reactive that they are never found in nature as free elements. The metals in the middle of the activity series (Zn,Fe,Pb,etc.) are moderately reactive. They are found in the earth’s crust mainly as oxides, sulphides or carbonates. The ores of many metals are oxides. This is because oxygen is a very reactive element and is very abundant on the earth.
