Unit 5-Test Tomorrow;)

Front

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 is the molecular shape of HCl?

Back

HCl has a linear molecular shape.

Front

What is the molecular shape of water (H2O)?

Back

The molecular shape of water (H2O) is bent due to the two lone pairs of electrons on the oxygen atom.

Front

What is the shape of a tetrahedral molecule?

Back

A tetrahedral molecule has four bonds arranged around a central atom, forming a shape like a pyramid with a triangular base.

Front

What is the chemical formula for Antimony tribromide?

Back

The chemical formula for Antimony tribromide is SbBr3.

Front

What is the shape of formaldehyde (CH2O)?

Back

Formaldehyde (CH2O) has a trigonal planar shape.

Front

What determines the molecular shape of a molecule?

Back

The molecular shape is determined by the arrangement of electron pairs around the central atom, according to VSEPR theory.

Front

What is VSEPR theory?

Back

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

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, resulting in a positive and negative end.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule is a molecule that does not have a net dipole moment, often due to symmetrical distribution of charge.
