Front

What is a resonance structure?

Back

A resonance structure is one of two or more valid Lewis structures for a molecule that cannot be represented accurately by a single Lewis structure. Resonance structures differ only in the placement of electrons.

Front

Which compound is best represented with resonance structures?

Back

SO₃²⁻ (sulfite ion) is best represented with resonance structures.

Front

What type of solid does not conduct electricity until it is melted or dissolved in water?

Back

Ionic solids do not conduct electricity until they are in liquid form or dissolved in an aqueous solution.

Front

What is the most polar bond?

Back

The Na-O bond is considered the most polar bond among common bonds.

Front

What are the characteristics of gases?

Back

Gases generally have low density, are compressible, and fill the volume of their container.

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.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is the difference between ionic and covalent bonds?

Back

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

Front

What is the formula for sodium hydroxide?

Back

The formula for sodium hydroxide is NaOH.

Front

What types of bonds are present in NaOH?

Back

NaOH contains both ionic bonds (between Na⁺ and OH⁻) and covalent bonds (within the hydroxide ion, OH⁻).
