Ionic Bonding

Front

What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions, typically formed when electrons are transferred from one atom to another.

Front

What are ionic compounds?

Back

Ionic compounds are substances formed from the electrostatic attraction between cations (positively charged ions) and anions (negatively charged ions).

Front

What is a characteristic property of ionic compounds?

Back

Ionic compounds form hard, brittle crystals with characteristic shapes.

Front

Front

What is the formula for ammonium phosphate?

Back

The formula for ammonium phosphate is (NH4)3PO4.

Front

What is the formula for aluminum sulfite?

Back

The formula for aluminum sulfite is Al2(SO3)3.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions, while anions are negatively charged ions.

Front

What is the octet rule in ionic bonding?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What is the role of electronegativity in ionic bonding?

Back

Electronegativity is the tendency of an atom to attract electrons; in ionic bonding, a large difference in electronegativity between two atoms leads to electron transfer.
