What is a Lewis Dot Structure?

Back

A Lewis Dot Structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Front

What does VSEPR stand for?

Back

VSEPR stands for Valence Shell Electron Pair Repulsion, a theory used to predict the geometry of individual molecules.

Front

What is the significance 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

How do you determine the formula of an ionic compound?

Back

The formula of an ionic compound is determined by the charges of the ions involved, ensuring that the total positive charge equals the total negative charge.

Front

What is the molecular geometry of a molecule with four bonding pairs and no lone pairs?

Back

The molecular geometry is Tetrahedral.

Front

What is the charge of a cesium ion?

Back

The charge of a cesium ion (Cs) is +1.

Front

What is the charge of a nitride ion?

Back

The charge of a nitride ion (N) is -3.

Front

How do you represent a cation in a Lewis Dot Structure?

Back

A cation is represented by removing the appropriate number of electrons from the Lewis Dot Structure of the neutral atom.
