Basic Chemistry Practice Test: Chemistry of the Nonmetals — Flashcards

Here are some other properties of nonmetals:
Electronegativity: Nonmetals are highly electronegative, which means they have a high ability to draw bonding electrons to themselves.
Ionization energy: Nonmetals have high ionization energy.
Reaction with other elements: Nonmetals tend to gain or share electrons with other elements or compounds when they react. They form anions (negatively charged ions) by pulling electrons away from metals.
Reaction with oxygen: Nonmetals form acidic or neutral oxides with oxygen. The acidic oxides dissolve in water to form acids.
Reaction with salt solutions: When reacting with salt solutions, a more reactive non-metal displaces a less reactive non-metal from its salt solution. 

Some examples of nonmetals include: Hydrogen, Carbon, Oxygen, Helium, Nitrogen, Bromine, Sulfur.
