Use of Metals - I

We know that elements can be of two types: Metals and Non-metals

Metals are those who possess certain metallic properties like hardness, ductility, malleability. They are also conductors of electricity and heat

Here, we will discuss the different uses of a few important metals

Let us begin with Iron

Iron is one of the most useful metals found in the world

It is extensively mined and converted to a number of products

Even our blood needs Iron

The oxygen carrying pigment Haemoglobin has Iron as its central metal atom

Thus, Iron plays a big role in respiration of red-blooded organisms

Next, we have Magnesium

Magnesium has a lot of uses in the pharmaceutical industry

We are all familiar with Milk of Magnesia which uses Magnesium as an active ingredient

It is used as a laxative

Magnesium is also used as a laboratory reagent

Magnesium is the central atom of the green plant pigment Chlorophyll

And it plays a major role in the process of photosynthesis

Thus, Magnesium is essential in trapping solar energy and establishing the food chain in the living world

Revision

Metals are those who possess certain metallic properties like hardness, ductility, malleability. They are also conductors of electricity and heat

Iron is the central atom in the red blood pigment Haemoglobin and helps in the process of respiration

While Magnesium is the central atom of the green plant pigment Chlorophyll which helps in the process of photosynthesis
