Iron is a
lustrous, ductile, malleable, silver-gray metal
(group VIII of the periodic table). It is known to exist in four distinct crystalline forms. Iron rusts in damp air, but not in dry air. It dissolves readily in dilute acids.
What are 5 chemical properties of metals?
- The density of metals is usually high.
- Metals are malleable and ductile.
- Metals form an alloy with other metals or non – metals.
- Some metals react with air and corrode. …
- Metals are good conductors of heat and electricity. …
- Generally, metals are in a solid state at room temperature.
What are 5 uses of iron?
Uses of iron
Iron is used to make alloy steels like carbon steels with additives such as nickel, chromium, vanadium, tungsten, and manganese. These are used to make bridges, electricity pylons, bicycle chains, cutting tools and rifle barrels. Cast iron contains 3–5% carbon. It is used for
pipes, valves, and pumps
.

What is the main use of iron?
Iron is an enigma – it rusts easily, yet it is the most important of all metals. 90% of all metal that is refined today is iron. Most is used to
manufacture steel
, used in civil engineering (reinforced concrete, girders etc) and in manufacturing.
What are chemical properties of steel?
Carbon is the principal hardening element in steel.
Hardness and strength increase proportionally
as Carbon content is increased up to about 0.85%. Carbon has a negative effect on ductility, weldability and toughness. Carbon range in ULC Steel is usually 0.002 – 0.007%.
What are chemical properties of a metal?
| Metals Nonmetals | They have 1, 2 or 3 electrons in the valence shell. So they can lose electrons easily. Nonmetals own more than 4 electrons in their valence shell. So they can easily gain electrons. | Metals produce the basic oxides These forms acidic oxide. |

What are the 10 properties of metals?
- Metals can be hammered into thin sheets. …
- Metals are ductile. …
- Metals are a good conductor of heat and electricity.
- Metals are lustrous which means they have a shiny appearance.
- Metals have high tensile strength. …
- Metals are sonorous. …
- Metals are hard.
What are 5 interesting facts about iron?
- Iron is the second most abundant of all metals on Earth. …
- Iron is the fourth most common element by mass. …
- Iron is the main component of meteorites. …
- Iron’s scientific name is ferrum. …
- In history, iron describes an entire period of human development. …
- You can’t make steel without iron.
Why is iron called ferrous?
Outside chemistry, “ferrous” means
generally “containing iron”
. The word is derived from the Latin word ferrum (“iron”). Ferrous metals include steel and pig iron (with a carbon content of a few percent) and alloys of iron with other metals (such as stainless steel).
What are the chemical properties?
A chemical property is
a characteristic of a particular substance that can be observed in a chemical reaction
. … A chemical change or reaction is a process in which one substance changes to another substance. In this process, the characteristics of the substances change, and this is when chemical properties are observed.
Why is copper a CU?
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is
a soft, malleable, and ductile metal with very high thermal and electrical conductivity
. … Coper (Old English) and copper were derived from this, the later spelling first used around 1530.
Why is iron so reactive?
From the atomic structure of iron,
its reactivity is mediocre
, having two possible forms of bonding in its excited electronic state. … Iron is also very easily oxidised by other elements (most of the time), hence iron is naturally found in the form of compounds when mined.
How is iron used by humans?
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. … It is used in kitchen cutlery, appliances and cookware such as stainless steel pans and skillets.
