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.

Front

What shape does SiCl4 have?

Back

SiCl4 has a tetrahedral shape.

Front

Is this a correct dot diagram for oxygen (O)?

Back

False. The correct dot diagram for oxygen should show 6 valence electrons.

Front

What is the molecular geometry of H2S?

Back

H2S has a bent molecular geometry.

Front

What is the molecular shape of a molecule with 2 bonding pairs and no lone pairs?

Back

Linear.

Front

What is the bond angle in a tetrahedral molecular geometry?

Back

Approximately 109.5 degrees.

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 the VSEPR theory?

Back

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

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 molecular geometry of NH3?

Back

NH3 has a trigonal pyramidal molecular geometry.
