Iron is main ingredient of earth and it is the fourth most abundant element in the earth's crust.the source of iron is low oxygen enviroment .if iron to be fresh it's surface is bright silver but in the stifling atmosfer it is oxidized.the chemical symbol of iron is fe and it is a chemical element. The atomic number of iron is 26. The density of iron is 7872 kg/m.

The pecullarite of iron is :

Iron has a smooth silver surface .but it becomes brown when combined with oxygen of air. If we add proper valuse of other materiales to iron ,steel is achived. Iron is main ingredient of earth. pure iron is steel. pure iron is found less in the earth. most iron is oxidized in the presence of oxygen and moisture. if we want to find iron steel we need to remove oxygen from natural quarry stone.

Mechanical properties of iron:

Mechanical properties of iron are examined with different testes like bernil taste and rakoul taste or tensile strengh tests.The result of these tests are consistend with each other. the measurment indicate that the mechanical properties of iron depend on purity. if we add very little carbon to the crystal the resistance of the crystal increases. the hardness of the crystal can also increase by 20%.

The most refined industrial iron has a roughtly 20 between 30 percent hardness.

Iron in plants :

iron is one of the essential issues for plans life.If  the plants dont get enough iron iron suffer from iron deficiency .In this time action of plants photosynthesis get into trouble.Iron is needed to grow plants. The role of iron in the chlorophyll of plants is important.

The signs of lack of iron in plants:

If iron is not absorbed in plants , leaf chlorophyll is reduced  and leafs leaves yellow. as iron in the plants is not dynamic else these are firse seen in fresh and young leafs. Except for of iron ,magnaese dificiency causes problems.
