Molecular Geometry

Front

What is the octet rule?

Back

The octet rule states that most elements need 8 valence electrons to achieve a stable electron configuration, similar to that of noble gases.

Front

What is the shape of a molecule with four bonded pairs and no lone pairs?

Back

Tetrahedral.

Front

What type of bond is formed between two nonmetals?

Back

Covalent bond.

Front

What is the molecular geometry of H2S?

Back

Bent.

Front

What is the shape of SiCl4?

Back

Tetrahedral.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have an uneven distribution of charge, while nonpolar molecules have an even distribution of charge.

Front

What is a lone pair in molecular geometry?

Back

A lone pair is a pair of valence electrons that are not shared with another atom.

Front

What is the VSEPR theory?

Back

Valence Shell Electron Pair Repulsion (VSEPR) theory predicts the shape of molecules based on the repulsion between electron pairs.

What is the geometry of a molecule with two bonded pairs and two lone pairs?

Back

Bent.

Front

What is the bond angle in a tetrahedral molecule?

Back

Approximately 109.5 degrees.
