Characteristics of metal non metal and metalloids
What characteristics are nonmetals?
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 metal and nonmetal and metalloid?
The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids. When elements combine to form compounds, there are two major types of bonding that can result.
Which is characteristic of metal and nonmetal?
Physical properties
| Metals | Non-metals |
|---|---|
| Shiny | Dull |
| High melting points | Low melting points |
| Good conductors of electricity | Poor conductors of electricity |
| Good conductors of heat | Poor conductors of heat |
What is the characteristic of metalloid?
Properties. Metalloids usually look like metals but behave largely like nonmetals. Physically, they are shiny, brittle solids with intermediate to relatively good electrical conductivity and the electronic band structure of a semimetal or semiconductor.
What are 5 characteristics of metal?
Metals are lustrous, malleable, ductile, good conductors of heat and electricity.

What are the 10 characteristics of non-metals?
Properties of Non-metals
- Non-metals cannot be hammered into thin sheets. …
- Non-metals are not ductile. …
- Non-metals are poor conductors of heat and electricity.
- Non-metals are not lustrous which means they are not shiny. …
- Non-metals have low tensile strength. …

What are three characteristics of nonmetals?
Nonmetals have properties opposite those of the metals. The nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity, and tend to gain electrons in chemical reactions.
What are 4 common properties of nonmetals?
Properties of Nonmetals
Nonmetals have high ionization energies and electronegativities. They are generally poor conductors of heat and electricity. Solid nonmetals are generally brittle, with little or no metallic luster. Most nonmetals have the ability to gain electrons easily.

What are the characters of metals?
- good conductors of heat and electricity.
- ductile (can be drawn into wires) and malleable (can be hammered)
- metals are solid at room temperature (except Mercury, it is a liquid state)
- high tensile strength.
- usually lustrous/shiny.
What are the 5 differences between metals and nonmetals?
Differences Between Metals And Non-metals
| Metals | Non-metals |
|---|---|
| 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 |
| These are shiny | These are non-lustrous except iodine |
| Electropositive in nature | Electronegative in nature |
What are the six metalloids?
The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium, and astatine.
