Covalent Bonding Review

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

What is the Lewis structure of a molecule?

Back

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

What is the molecular shape of water (H2O)?

Back

The molecular shape of water is bent due to the two lone pairs of electrons on the oxygen atom.

Front

What is the shape of carbon dioxide (CO2)?

Back

The shape of carbon dioxide is linear.

Front

What is a tetrahedral molecular shape?

Back

A tetrahedral molecular shape occurs when a central atom is bonded to four other atoms, with bond angles of approximately 109.5 degrees.

Front

What is the molecular geometry of BF3?

Back

The molecular geometry of BF3 (boron trifluoride) is trigonal planar.

Front

What type of bond is formed between sodium (Na) and bromine (Br)?

Back

An ionic bond is formed between sodium and bromine.

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 the significance of lone pairs in molecular geometry?

Back

Lone pairs can affect the shape of a molecule by repelling bonding pairs of electrons, altering bond angles.

Front

What is the VSEPR theory?

Back

The Valence Shell Electron Pair Repulsion (VSEPR) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs.
