Because it is strong and durable, the metal iron (element #26) was widely used in ancient times. It was the first metal early humans learned to use for tools. In modern uses, it is mostly found in the alloys of "steel" (iron with a small percentage of carbon). The weakness of both iron and steel is that they can be oxidized (rust), and various metals are added to steel to reduce this. The oxidation of iron plays an important part in human physiology. The iron-based protein "hemoglobin" is found in red blood cells, which enables these cells to absorb oxygen and carry it to other cells in the body. When there is oxygen in the blood, it is a bright red color due to the oxygen's combination with the iron.

Facts about nails that rust?
Nails rust when exposed to moisture and oxygen, as the iron in the nail reacts with the oxygen in the air to form iron oxide. Rust weakens the nail, making it more prone to breaking or bending. It is important to use rust-resistant coatings or materials like galvanized or stainless steel nails for outdoor or wet environments to prevent rusting.
Why is charcoal important to smelting iron?
Charcoal is important for smelting iron because it provides the high temperatures needed to melt the iron ore and extract the metal. Charcoal also acts as a reducing agent, helping to remove oxygen from the iron ore to produce molten iron. In addition, charcoal burns cleaner and hotter than wood, making it more efficient for smelting.
