I am afraid the question is not very clear.
However if you are talking about why an Element (and here element means a proper chemical Element like Oxygen, Iron or Gold) is classified as an element.
Physically though there is no single property except for a chemical characteristic. All METALS easily lose an electron or more to form positively charged ions and readily form bonds which are called metallic bonds. If this answer is too scientific for you, do not worry.
The thing to remember here is there are metals like Sodium, which in their pure form dont look like quite like the traditional image of a metal. Like an iron bar, or may be a gold slab. Mercury also qualifies as a metal but is a liquid at room temperature.
So, please clarify your question or be satisfied. Wikipedia has quite a good insight to this question.

Metals are usually:
* Ductile (can form wire)
* Malleable (can be molded and reshaped)
* Conducts electricity
* Has a luster (shine)
All the properties of metals are: Shiny Malleable Ductile High density Brittle Solid Thermal Conductors and a few more but not sure exactly what there are Sorry about that =]
metallic luster, malleable (ability to be flattened), conductivity for heat and electricity, solid at STP, and low ionization and electronegativity

Where are the metals and non metals on the periodic table?
metals on left, non-metals on right, some others in middle.
Name metals which do not react with oxygen?
Some metals that do not react with oxygen include gold, platinum, and silver. These metals are considered to be noble metals because they are resistant to oxidation.
What are properties of semimetal?
Semi-metals have some properties of metals and some from nonmetals. Semi-metals are solid at room temperature. They are also brittle, hard, and somewhat reactive.
Would you name some metals that react with acids?
Some of these metals are: Calcium, Magnesium, Sulfur, Sodium, Potassium, ...

Why are some metals found as pure metals and some metals are not found as pure metals?
because u have to with some metals make a mixs ture so there
Do some metals corrode?
Yes it does. but not all metals.
Where are the metals and non metals on the periodic table?
metals on left, non-metals on right, some others in middle.
What are some examples of hard solid metals?
Some examples of hard solid metals include iron, steel, titanium, and tungsten. These metals are known for their strength, durability, and resistance to deformation.
Do acids corrode some metals?
Yes it does. but not all metals.
Name metals which do not react with oxygen?
Some metals that do not react with oxygen include gold, platinum, and silver. These metals are considered to be noble metals because they are resistant to oxidation.
Can all minerals be a gemstones?
No not all. Some minerals are metals.
How do some metals become super conductors?
Some metals become a super conductor when you freeze them
What has some of the properties of both metals and non metals'?
Metalloids have some properties of both metals and nonmetals. They can exhibit characteristics of metals, such as conductivity, and characteristics of nonmetals, such as brittleness. Metalloids are found in a staircase pattern on the periodic table between metals and nonmetals.
