Metals is elements that share the property of being metallic.

Metal atoms have one, two or three electrons in their outer shells. Thir cores (nuclei plus inner shells) are held in a rigid crystal lattice like a jungle gym. This gives the metal many of its physical properties such as hardness (with the exception of mercury) and shininess. Though the cores of the metal atoms are held in a fixed pattern, the outer shell electrons aren't held any more tightly by the core they came from than by any other core. They are therefore free to wander around. This situation gives metals their one defining property - the ability to conduct electricity. All metals, including mercury, conduct or carry electricity. Electricity is the movement of electrons. Although the outer shell electrons of a metal are free to move they will not do so unless an appropriate outside force is applied. Remember Newton's first law? That force is called EMF or electromotive force and can be supplied by a battery, generator or friction between non-conductors as is the case with static electricity.

Metals are the elements on the left side of the periodic table. They give away electrons, conduct electricity and heat, they are malleable and ductile. The center of the table is called the transition metals.

Metals are the elements(except hydrogen)which form positive ions by losing electons.Metals are good conductors of heat and electricity.Oxides of metals are basic in nature.They are malleable and ductile.They posses high density.They are lustorous and sonorous.All metals are solid except mercury.Ex.Gold,Iron,Silver,Aluminium

Metals have overlapping conduction and valence bands. Conduction bands allow the transport of electrons over long distances, so having the valence bands (where the valence electrons are) overlap them means that metals are good electrical conductors.

A metal is an element that has high electrical conductivity, luster, and malleability, which readily loses electrons to form positive ions (cations).

If your refering to steel, iron,etc.

Then metals are a combination of elements. Our world is made up of a number of elements. Hydrogen, Helium, etc. Just like baking a cake you can combine these elements to create more elements all having different charicteristics.

For example, Hydrogen and Oxygen are two elements both gases, but when you combine them they become H20(Water) at which point it takes on a new charicteristic, it becomes a liquid.

Metals are just a combination of elements that takes on a new form......a solid.

Metals are materials whose inter-atomic bonds are metallic.
