Answer

Silicon is second

Answer

Iron is the second most abundant Metal in the earth's crust. It is found in the molten form inside the crust of the earth. In the presence of air and moisture, it forms it's oxide but the alloy of steel is widely used as pipes, it is unreactive in nature.

Answer

Lron (Fe)

Answer

Sometimes silicon acts as a metal for example, it form an oxide This would make it the most abundant metal in the earth  crust where it form 28% of crustal rocks . The second most abundant metal then ,8% would be aluminium .If one discounts silicon accepting that a non metal then aluminium would be the most abundant metal followed by iron 5% in second place

Answer

Iron (Fe)

Iron is the second most abundant metal present in the Earth's crust after aluminum. Here are some key points about iron:

Iron in the Earth's Crust:
- Iron is a chemical element with the symbol Fe and atomic number 26.
- It is a crucial element in the formation of rocks and minerals, and it is found in various ores such as hematite, magnetite, and siderite.
- Iron is primarily found in the form of iron oxides, which are compounds of iron and oxygen.

Importance of Iron:
- Iron is an essential element for many living organisms, including humans. It is a key component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body.
- Iron is also used in various industrial applications, such as in the production of steel and other alloys.

Extraction of Iron:
- Iron is typically extracted from iron ore through a process called smelting, where the ore is heated in a blast furnace with carbon to remove the oxygen and extract the iron metal.
- The extracted iron can then be used in various industries for manufacturing purposes.

Conclusion:
Iron is a vital metal that plays a significant role in both natural processes and human activities. Its abundance in the Earth's crust makes it a crucial element for various applications, ranging from biological functions to industrial processes.
