Ionic Bonding

Front

What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions) that occurs when electrons are transferred from one atom to another.

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.

Front

How do you determine the charge of an ion?

Back

The charge of an ion is determined by the difference between the number of protons (positive) and electrons (negative) in an atom. If there are more protons, the ion is positive (cation); if there are more electrons, the ion is negative (anion).

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell of eight electrons, achieving a stable electron configuration.

What is the significance of Lewis structures in ionic compounds?

Back

Lewis structures visually represent the arrangement of electrons in a molecule, showing how ions are formed and how they bond in ionic compounds.
