Revised - Unit 4 Chemical Bonding Review

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

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.

Front

What is the Lewis electron-dot structure?

Back

The Lewis electron-dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What does STP stand for in chemistry?

Back

STP stands for Standard Temperature and Pressure, which is defined as 0 degrees Celsius (273.15 K) and 1 atmosphere pressure.

Front

What is the significance of intermolecular forces?

Back

Intermolecular forces are the forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions) that influence the physical properties of substances.

Front

What is the formula for magnesium fluoride?

Back

The formula for magnesium fluoride is MgF2.

Front

What happens during the formation of a bond?

Back

During the formation of a bond, energy is released, which stabilizes the atoms involved.

Front

What is the role of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms.

Front

What is an example of a compound where electrons have been transferred?

Back

An example of a compound where electrons have been transferred is sodium oxide (Na2O).

Front

How do you determine the strength of intermolecular forces?

Back

The strength of intermolecular forces can be determined by the type of molecules involved and their polarity; stronger forces lead to higher boiling and melting points.
