Which element is both metal and nonmetal?
Key Concepts and Summary 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.
Which class of metal behaves like both a metal and nonmetal?
Metalloids
Metalloids may act either like metals or nonmetals in chemical reactions. Most metalloids have some physical properties of metals and some physical properties of nonmetals.
Is atomic number 12 a metal or nonmetal?
The element having atomic mass 12 is Magnesium. and 2nd group elements are all metals. Therefore, an element having atomic number 12 is Metal.
What substance can act as a metal or nonmetal?
They can form alloys with other metals. Some metalloids, such as silicon and germanium, can act as electrical conductors under the right conditions, thus they are called semiconductors….Metalloids.
| Metals | Non-metals | Metalloids |
|---|---|---|
| Gold | Oxygen | Silicon |
| Silver | Carbon | Boron |
| Copper | Hydrogen | Arsenic |
| Iron | Nitrogen | Antimony |
What has both metallic and nonmetallic properties?
metalloid. a nonmetal that in combination with a metal forms an alloy. an element that has both metallic and nonmetallic properties, as arsenic, silicon, or boron.
What are the different properties of both metals and non metals?
Physical properties
| Metals | Non-metals |
|---|---|
| Good conductors of electricity | Poor conductors of electricity |
| Good conductors of heat | Poor conductors of heat |
| High density | Low density |
| Malleable and ductile | Brittle |
What properties have both metals and nonmetals?
Metalloids share characteristics of both metals and non-metals and are also called semimetals. Metalloids are typically semi-conductors, which means that they both insulate and conduct electricity. This semi-conducting property makes Metalloids very useful as a computer chip material.
What are the different properties of both metals and non-metals?
Is Cl A metal?
Chlorine is a non-metal. The element chlorine is a yellowish-green gas which is extremely reactive and react with various metals.
How do you identify metals and nonmetals?
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.
What are the similarities between metals and nonmetals?
Metals tend to be strong and conductive, and have high melting points. However, like nonmetals, their forms occur as a distinct combination of electrons, protons and neutrons. All elements, metal or otherwise, can change state or react.
Which element has both metallic and nonmetallic properties RB RN Si Sr?
The metalloids; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are the elements found along the step like line between metals and non-metals of the periodic table. Metalloids have properties of both metals and non-metals.
