What is the reactivity of metalloids?
The reactivity of the metalloids depends on the element with which they are reacting. For example, boron acts as a nonmetal when reacting with sodium yet as a metal when reacting with fluorine. The boiling points, melting points, and densities of the metalloids vary widely.
What is an example of a reactive nonmetal?
The element fluorine is the most reactive nonmetal. It is not found in nature as a free element. Fluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances.
What are the example of metal nonmetal and metalloids?
Metalloids
Metals | Non-metals | Metalloids |
---|---|---|
Silver | Carbon | Boron |
Copper | Hydrogen | Arsenic |
Iron | Nitrogen | Antimony |
Mercury | Sulfur | Germanium |
What are 3 metalloids examples?
Boron, silicon, germanium, arsenic, antimony, and tellurium are commonly recognised as metalloids.
Which of the metalloids are considered highly reactive?
The first three elements—oxygen (O), sulfur (S), and selenium (Se)—are nonmetals. They are followed by tellurium (Te) (Figure below), a metalloid, and polonium (Po), a metal. All group 16 elements have six valence electrons and are very reactive.
What are metalloids give two examples?
Metalloids include boron, silicon, germanium, arsenic, antimony, and tellurium. An element that isn’t a metal yet has certain metal-like qualities. Boron, silicon, germanium, arsenic, antimony, tellurium, and polonium are examples of metalloids.
What is the reactivity of non metals?
Nonmetals are also poor conductors of heat, and solid nonmetals are dull and brittle. Some nonmetals are very reactive, whereas others are not reactive at all. It depends on the number of electrons in their outer energy level. Reactive nonmetals tend to gain electrons.
Which is most reactive metal?
The most reactive metal on the periodic table is francium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium.
What are 5 examples of nonmetals?
Five Nonmetals
- Nitrogen.
- Oxygen.
- Helium.
- Sulfur.
- Chlorine.
What is a non metal example?
Hydrogen, chlorine, fluorine, carbon, nitrogen, phosphorus, selenium are examples of non-metal.
