What are the 3 characteristics of metals?
Metals are
good conductors of heat and electricity
, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire). Most of the metals are solids at room temperature, with a characteristic silvery shine (except for mercury, which is a liquid).

What are the five uses of metals?
- Uses of metals:
- (i) Lead metal is used in making car batteries.
- (ii) Zinc is used for galvanizing iron to protect it from rusting.
- (iii) Iron, copper and aluminium are used to make utensils.

What is the unique property of metal?
Malleability & Ductility – metals can bend and change shape without breaking. Conductivity – metals tend to be good conductors of heat and electricity.
Luster
– metals have a unique, shiny visual appearance. Magnetism – Many metals are ferromagnetic or paramagnetic.
What are metals and examples?
Metals are materials holding or possessing the characteristics of being shiny, hard, fusible, malleable, ductile, etc. Few examples of metals (materials) are –
Gold, Silver, Aluminium, Copper, Iron, etc
.
What are 3 characteristics of nonmetals?
- High ionization energies.
- High electronegativities.
- Poor thermal conductors.
- Poor electrical conductors.
- Brittle solids—not malleable or ductile.
- Little or no metallic luster.
- Gain electrons easily.
- Dull, not metallic-shiny, although they may be colorful.
What are called metals?
In chemistry, a metal is
an element that readily forms positive ions (cations) and has metallic bonds
. Most elements on this line are metalloids, sometimes called semi-metals; elements to the lower left are metals; elements to the upper right are nonmetals. …
Are all metals shiny?
All metals have a shiny appearance
(at least when freshly polished); are good conductors of heat and electricity; form alloys with other metals; and have at least one basic oxide.
How do you distinguish between metals and nonmetals?
| Metals Nonmetals | Metals are generally malleable and ductile. Non metals are generally brittle and can break down into smaller pieces. | They are shiny and lustrous. They are not shiny and are non lustrous except iodine. | They are electropositive in nature. They are electronegative in nature. |
