Answer:

sorryyyy but I dont noo this

Answer 2

Explanation:

From being a crucial building block of steel to nourishing plants and helping carry oxygen in your blood — iron is always busy helping sustain life on Earth.

Iron is a brittle, hard substance, classified as a metal in Group 8 on the Periodic Table of the Elements. The most abundant of all metals, its pure form rapidly corrodes from exposure to moist air and high temperatures. Iron is also the fourth most common element in Earth's crust by weight and much of Earth's core is thought to be composed of iron. Besides being commonly found on Earth, it is abundant in the sun and stars, according to the Los Alamos National Laboratory. Iron is crucial to the survival of living organisms, according to Jefferson Lab. In plants, it plays a role in the production of chlorophyll. In animals, it is a component of hemoglobin — a protein in blood that carries oxygen from the lungs to the tissues in the body.

Ninety percent of all metal that is refined these days is iron, according to the Royal Society of Chemistry. Most of it is used to make steel — an alloy of iron and carbon — which is in turn used in manufacturing and civil engineering, for instance, to make reinforced concrete. Stainless steel, which contains at least 10.5 percent chromium, is highly resistant to corrosion. It is used in kitchen cutlery, appliances and cookware such as stainless steel pans and skillets. The addition of other elements can provide steel with other useful qualities. For instance, nickel increases its durability and makes it more resistant to heat and acids; manganese makes it more durable, whereas tungsten helps it maintain hardness at high temperatures, according to Jefferson Lab.
