Nonmetals are chemical elements that are defined as being diametrically opposed to metalsThese elements lose the qualities that characterize metals.
The non-metals are:
Argon
Astatus
Sulfur
Bromine
Carbon
Chlorine
Krypton
Fluorine
Match
Helium
Hydrogen
Neon
Nitrogen
Oxygen
Radon
Selenium
Xenon
Iodine
Nonmetals can range from gases to chlorides.

8 Characteristics of non-metals:
Acidity. They are characterized by their acidity, since the vast majority of non-metal oxides form some acidic solutions.
Brilliance. By their nature, non-metals have low brilliance unlike metals.
Hot. Heat transmission is lower in non-metals.
Conductivity. Nonmetals are not good conductors Nonmetals are distinguished primarily by not being good conductors, although this does not mean that they cannot conduct.
Ductility. Non-metals do not have the ability to bend or stretch, so sheets cannot be made by plastic deformation.
Gases. These elements are mostly gases.
Chemical properties. Among the chemical properties of nonmetals is that in their last layer they have from 4 to 7 electrons and when ionized they can acquire a negative charge and with oxygen they form non-metallic or anhydride oxidations.
