1st semester final review #6: Ionic vs Molecular Compounds

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. They typically form between metals and nonmetals.

Front

What is a molecular compound?

Back

A molecular compound is a chemical compound where atoms are bonded together by covalent bonds, typically formed between nonmetals.

Front

What is the octet rule?

Back

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

Front

How do you determine the electron-dot formula for a compound?

Back

The electron-dot formula, or Lewis structure, represents the valence electrons of atoms within a molecule. It shows how the electrons are arranged among the atoms.

Front

What is the significance of the IUPAC naming system?

Back

The IUPAC naming system provides a standardized way to name chemical compounds, ensuring that each compound has a unique and universally accepted name.

Front

What is a polyatomic ion?

Back

A polyatomic ion is a charged species composed of two or more atoms covalently bonded, which can act as a single unit in chemical reactions.

Front

What is the electron configuration of calcium?

Back

The electron configuration of calcium (Ca) is 1s² 2s² 2p⁶ 3s², indicating it has two electrons in its outermost shell.

Front

What happens to calcium when it reacts to form an ionic compound?

Back

Calcium tends to lose two electrons to achieve a stable electron configuration, forming a Ca²⁺ ion.

Front

What is the formula for magnesium fluoride?

Back

The formula for magnesium fluoride is MgF₂, indicating one magnesium ion and two fluoride ions.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.
