Aluminum sulfide

Front

Which element is most likely to form a cation?

Back

Sodium

Front

What type of elements are anions and what charge do they carry?

Back

Anions are nonmetals that form negative ions by gaining electrons.

Front

Which element is most likely to form a negative ion?

Back

Oxygen

Front

What is the general rule for naming binary ionic compounds?

Back

The name of the cation (metal) is followed by the name of the anion (nonmetal) with its ending changed to '-ide.'

Front

What is a cation?

Back

A cation is a positively charged ion formed when an atom loses electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion formed when an atom gains electrons.

Front

How do you determine the charge of a cation from its position in the periodic table?

Back

Cations typically form from metals, which lose electrons; the charge is equal to the number of electrons lost.

Front

What is the significance of valence electrons in ionic bonding?

Back

Valence electrons determine how atoms interact and bond; atoms tend to lose, gain, or share valence electrons to achieve stability.
