Five physical properties of non-metals are:
- Non-metals are brittle. …
- Non-metals are bad conductors of heat and electricity (except graphite).
- Non-metals are non-lustrous (dull) and cannot be polished (except iodine).
- Non-metals may be solids, liquids or gases at room temperature.
- Non-metals are neither tough nor strong.
What are the 10 differences between metals and nonmetals?
Differences Between Metals And Non-metals
| Metals | Non-metals |
|---|---|
| These are solids at room temperature except mercury | These exist in all three states |
| These are very hard except sodium | These are soft except diamond |
| These are malleable and ductile | These are brittle and can break down into pieces |
What are the 12 properties of metals?
Properties of Metals
- Metals can be hammered into thin sheets. It means they possess the property of malleability.
- 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 characteristics of metal?
- Good electrical conductors and heat conductors.
- Malleable – can be beaten into thin sheets.
- Ductile – can be stretched into wire.
- Possess metallic luster.
- Opaque as thin sheet.
- Solid at room temperature (except Hg).
What are characteristic 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 22 non metals symbols?
List of Non-Metals (the Complete List)
| Non-metal | State at Room Temperature | Symbol |
|---|---|---|
| Oxygen | Gas | O |
| Fluorine | Gas | F |
| Chlorine | Gas | Cl |
| Bromine | Liquid | Br |
What are the characteristics of metals?
metal, any of a class of substances characterized by high electrical and thermal conductivity as well as by malleability, ductility, and high reflectivity of light. Approximately three-quarters of all known chemical elements are metals.
What is the general characteristics of metal?
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 properties are characteristics of metal?
Physical Properties of Metals
Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
What properties do most metals have?
Properties of Metals
- Metals have relatively high melting points. This explains why all metals except for mercury are solids at room temperature.
- Most metals are good conductors of heat. …
- Metals are generally shiny. …
- The majority of metals are ductile. …
- Metals tend to be malleable.
What are the characteristics of non-metals?
In the elemental form, non-metals can be gas, liquid or solid. They aren’t shiny (lustrous) and they don’t conduct heat or electricity well. Usually their melting points are lower than for metals, although there are exceptions. The solids usually break easily, and can’t bend like metals.
What is difference between metals and nonmetals?
Metals tend to be hard, metallic-looking solids, with high electrical and thermal conductivity values and high melting and boiling points. Nonmetals tend to be softer, often colorful elements. They may be solids, liquids, or gases.
