Properties of iron:

Iron is soft, bright white metal.

Its symbol is Fe, atomic number is 26 and atomic mass is 55.85 amu.

It is present in group 8 of periodic table.

It is used to make the steel.

It is malleable and ductile used to make the sheets.

It is good conductor of heat and electricity because of moveable electrons that can easily move from one to another atom.

Its density is 7.87 g/cm³.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
