Flashcard 2

Front

What type of bonding is present in ionic compounds?

Back

Ionic bonding occurs when electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions that attract each other.

Front

What is the solubility characteristic of ionic compounds in water?

Back

Ionic compounds typically dissolve readily in water, breaking apart into their constituent ions.

Front

How do ionic compounds conduct electricity?

Back

Ionic compounds conduct electricity when dissolved in water because the ions are free to move and carry an electric charge.

Front

What is the difference in size between positively and negatively charged ions in an ionic lattice?

Back

Negatively charged ions (anions) are generally larger than positively charged ions (cations) due to the addition of electrons.

Front

What is a Lewis diagram?

Back

A Lewis diagram is a representation of a molecule that shows the arrangement of electrons around atoms, including bonding and lone pairs.

Front

What does a formal charge indicate in a Lewis structure?

Back

Formal charge indicates the charge of an atom in a molecule, calculated based on the number of valence electrons, bonding electrons, and lone pair electrons.

Front

What is the significance of ionic radii in determining the strength of ionic bonds?

Back

The size of the ions (ionic radii) affects the strength of the ionic bond; smaller ions can get closer together, resulting in stronger attractions.

Front

What are intermolecular forces?

Back

Intermolecular forces are the forces of attraction or repulsion between molecules, affecting properties like boiling point and vapor pressure.

Front

How does temperature affect the vapor phase of a liquid?

Back

Increasing temperature increases the kinetic energy of particles, leading to more particles entering the vapor phase.

Front

What is the relationship between vapor pressure and intermolecular forces?

Back

Stronger intermolecular forces result in lower vapor pressure because fewer particles can escape into the vapor phase.
