| Sodium | Metal: very reactive |
| Calcium | Metal: very reactive |
| Magnesium | Metal: fairly reactive |
| Aluminium | Metal: fairly reactive |
What metals are found as ores?
Ore is a deposit in Earth’s crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.
What are the examples of reactive metals?
Reactivity Series of metals Chart
| Metal | Symbol | Reactivity |
|---|---|---|
| Calcium | Ca | Displaces H2 gas from water, steam and acids and forms hydroxides. |
| Sodium | Na | |
| Magnesium | Mg | Displaces H2 gas from steam and acids and forms hydroxides. |
| Aluminium | Al |
Where are reactive metals found?
The most reactive metals are found on the left of the periodic table, in the blue column, known as the alkali metals. Their reactivity increases as we go down column (group) one, shown in blue.
Where are ores found?
Ore can accumulate through geologic activity, such as when volcanoes bring ore from deep in the planet to the surface. This is called an internal process. Ore can also accumulate when seawater circulates through cracks in Earth’s crust and deposits minerals in the areas around hydrothermal vents.
How ores are found?
Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. Ore bodies are formed by a variety of geological processes generally referred to as ore genesis.
What is nature of metal oxide?
Metal oxides are basic nature. Some are amphoteric.
How are high reactivity metals extracted from ores?
The method used to extract a metal from its ore depends upon the stability of its compound in the ore, which in turn depends upon the reactivity of the metal. Electrolysis is commonly used to extract these metals and requires a lot of electric current (energy) to reduce them to extract the metal.
Why sulphide and carbonate ores are converted into oxides?
Carbonate and sulphide ores are usually converted into oxides during the process of extraction because extraction of metal is easier from their oxides rather than from their carbonates or sulphides.
