Ionic bonding

Front

What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions, typically formed when one atom donates 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.

How does aluminum (Al) form a bond?

Back

Aluminum forms a bond by losing three electrons to become a cation (Al³⁺).

Front

What charge does a sulfur ion have when it forms an ion?

Back

A sulfur ion typically gains two electrons to become an anion (S²⁻).

Front

What is the electron configuration of a calcium ion (Ca²⁺)?

Back

The electron configuration of Ca²⁺ is the same as that of argon, as it loses two electrons.

Front

What state of matter are ionic compounds at room temperature?

Back

Ionic compounds are typically solid at room temperature.

Front

What is the general property of ionic compounds?

Back

Ionic compounds generally have high melting and boiling points due to strong ionic bonds.

Front

What happens to the electrons in ionic bonding?

Back

In ionic bonding, electrons are transferred from one atom to another, resulting in the formation of cations and anions.

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 significant difference in electronegativity between two atoms leads to electron transfer.
