10 characteristics of nonmetals
Nonmetals are a group of chemical elements that are characterized by their low electrical conductivity, opacity, and tendency to gain electrons. Unlike metals, nonmetals tend to form covalent bonds rather than ionic bonds. In this article we will explore the main characteristics of non-metals, as well as their uses and applications in everyday life.
Main characteristics of nonmetals
- Low electrical conductivity
- Tendency to gain electrons
- Formation of covalent bonds
- Solid, liquid or gaseous state at room temperature
- They are generally neither malleable nor ductile.
- Relatively low melting and boiling point
- Some are very reactive
- They exist in nature in their pure state or in the form of compounds.
- They can be solids, liquids or gases at room temperature.

What are the most common nonmetals?
The most common nonmetals are oxygen, nitrogen, hydrogen, fluorine, chlorine, sulfur and phosphorus.
Are non-metals dangerous to health?
Some nonmetals, such as chlorine and fluorine, can be toxic in large quantities, but in general, nonmetals do not pose a health hazard in their natural form.
Are non-metals used in industry?
Yes, non-metals are used in the manufacture of plastics, cosmetics, medicines, among other products.
What is the difference between a metal and a non-metal?
The main difference between a metal and a non-metal is its ability to conduct electricity, its luster, and its malleability. Metals are good conductors of electricity, shiny and malleable, while non-metals are the opposite.
Why do nonmetals tend to gain electrons?
Nonmetals tend to gain electrons to complete their valence shell and reach a state of greater stability.
What applications do nonmetals have in everyday life?
Non-metals are used in the manufacture of plastics, electrical insulators, medicines, fuels and many other products that are part of our daily lives.
What are the states of nonmetals at room temperature?
Nonmetals can be solid, liquid or gaseous at room temperature, depending on each element.
What happens when non-metals react with metals?
Nonmetals tend to form compounds with metals, in which the nonmetals gain electrons and the metals lose them.
