Ionic Bonding

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically formed when one atom transfers electrons to another.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.

In aluminum oxide, which ion is the cation?

Back

The cation in aluminum oxide is [ Al ] +3.

Front

What does a subscript in a chemical formula indicate?

Back

A subscript indicates the number of atoms of an element in a molecule.

Front

What does a superscript in a chemical formula indicate?

Back

A superscript indicates the charge of an ion.

Front

What happens during the formation of an ionic bond?

Back

During the formation of an ionic bond, one atom transfers electrons to another atom, resulting in the formation of oppositely charged ions that attract each other.

Front

What is the role of electron transfer in ionic bonding?

Back

Electron transfer is crucial in ionic bonding as it leads to the formation of cations and anions, which then attract each other due to their opposite charges.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between charged ions, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the significance of 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, which is often the driving force behind ionic bonding.
