PreAP Bonding Exam 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

What is the 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 in the valence shell.

Front

What is the VSEPR shape and bond angle for a molecule with 2 bonding pairs and 0 lone pairs?

Back

Linear shape with a bond angle of 180 degrees.

Front

What is the VSEPR shape and bond angle for a molecule with 3 bonding pairs and 1 lone pair?

Back

Trigonal pyramidal shape with a bond angle of approximately 109 degrees.

Front

What are ionic compounds?

Back

Ionic compounds are formed when atoms transfer electrons, resulting in the formation of charged ions that attract each other, typically resulting in a neutral compound.

Front

How does Beryllium behave in ionic bonding?

Back

Beryllium will lose 2 valence electrons when forming an ionic bond.

Front

What is the bond angle in a tetrahedral molecule?

Back

The bond angle in a tetrahedral molecule is approximately 109 degrees.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is a lone pair of electrons?

Back

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

Front

What is the significance of the D block in the periodic table?

Back

The D block contains transition metals, which have partially filled d orbitals and can form various oxidation states.
