The elements boron, silicon, germanium, arsenic, antimony, and tellurium separate the metals from the nonmetals in the periodic table. These elements, called metalloids or sometimes semimetals, exhibit properties characteristic of both metals and nonmetals.
What are the similarities between metals and nonmetals?
Similarities between metals and non metals are: Both metals and non metals are elements . Both have the same atomic structure. Both share electrons to form molecules.
What properties do both metals and nonmetals have?
| Metals Non-metals | High melting points Low melting points | Good conductors of electricity Poor conductors of electricity | Good conductors of heat Poor conductors of heat | High density Low density |

What are the 5 characteristics of metals and nonmetals?
- 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 the 10 properties of metals?
- Metals can be hammered into thin sheets. ...
- Metals are ductile. ...
- Metals are a good conductor of heat and electricity.
- Metals are lustrous which means they have a shiny appearance.

What are the 5 metallic properties and explanation?
Metals are lustrous, malleable, ductile, good conductors of heat and electricity .
What do all metals have in common?
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.
What is difference between metal and nonmetal?
| Metals Non-Metals | Metals usually do not combine with hydrogen. Only a few reactive metals combine with hydrogen to form ionic metal hydrides. Non- metals react with hydrogen to form stable, covalent hydrides. |

Are metals brittle?
Metals. Some metals exhibit brittle characteristics due to their slip systems . ... Conversely, with fewer slip systems, less plastic deformation can occur, and the metal will be more brittle. For example, HCP (hexagonal close packed) metals have few active slip systems, and are typically brittle.
Is P metal or nonmetal?
| NUMBER SYMBOL ELEMENT | 15 P Phosphorus | 16 S Sulfur | 17 Cl Chlorine | 18 Ar Argon |

- malleable.
- ductile.
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.

- Most metals are good conductors of heat. ...
- Metals are generally shiny. ...
- The majority of metals are ductile. ...
- Metals tend to be malleable.
What are 3 characteristics of a metal?
Three characteristics of metals are their good conductivity, malleability, and shiny appearance . Metals are good conductors of heat and electricity,...
What are the unique properties of metal?
Hardness – metals tend to be hard and resistant to deformation. 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.
What are not properties of most metals?
| Metals Non-metals | Malleable or brittle Malleable (they bend without breaking) Brittle (they break or shatter when hammered) | Conduction of heat Good Poor (they are insulators) | Conduction of electricity Good Poor (they are insulators, apart from graphite) | Magnetic material Only iron, cobalt and nickel None |
