Covalent Bonding Review

Front

What are valence electrons?

Back

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

Front

How many valence electrons does oxygen have?

Back

Oxygen has 6 valence electrons.

Front

What is the molecular geometry of a molecule with two bonding pairs and one lone pair around the central atom?

Back

The molecular geometry is bent.

Front

What is the Lewis structure?

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.

Front

How many bonds does phosphorus typically form?

Back

Phosphorus typically forms three bonds.

Front

What is the significance of the central atom in molecular geometry?

Back

The central atom is the atom in a molecule that is bonded to other atoms and determines the overall shape of the molecule.

Front

What is the correct Lewis structure for PBr3?

Back

The correct Lewis structure for PBr3 shows phosphorus in the center with three bromine atoms bonded to it and one lone pair of electrons.

Front

What is the LD Diagram?

Back

The LD Diagram (Lewis Dot Diagram) represents the valence electrons of an atom and how they are arranged in a molecule.

Front

Which element typically forms a triple bond?

Back

Nitrogen typically forms a triple bond.

Front

What is the bond angle in a bent molecular geometry?

Back

The bond angle in a bent molecular geometry is typically less than 120 degrees.
