Covalent Bonding

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 electron dot structure?

Back

The electron dot structure, or Lewis structure, represents the valence electrons of atoms within a molecule, showing how they are shared or transferred.

What is the electron dot structure for water (H₂O)?

Back

H:O:H (with dots around O) represents the electron dot structure for water.

Front

What are dispersion forces?

Back

Dispersion forces are weak intermolecular forces that arise from temporary shifts in electron density in atoms or molecules.

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.

Front

What is a molecule with a single covalent bond?

Back

F₂ (Fluorine gas) is an example of a molecule with a single covalent bond.

Front

What is the definition of a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms, resulting in a molecule with a slight electrical dipole moment.

Front

What is an example of a non-polar covalent bond?

Back

An example of a non-polar covalent bond is the bond in O₂ (Oxygen gas).

Front

What type of bond is found in potassium fluoride (KF)?

Back

KF contains an ionic bond.

Front

What is the significance of electronegativity in covalent bonding?

Back

Electronegativity is a measure of an atom's ability to attract shared electrons; it determines the polarity of a bond.
