Bonding and VSEPR Theory Flashcard

Front

What is Ionic Bonding?

Back

Ionic Bonding involves the transfer of electrons between atoms, resulting in the formation of charged ions that attract each other.

Front

How does the bond in F₂ differ from KCl?

Back

F₂ is a covalent bond, where electrons are shared between atoms, while KCl is an ionic bond, formed by the transfer of electrons.

Front

What do valence electrons represent in bonding?

Back

Valence electrons are the outermost electrons of an atom that are involved in forming bonds with other atoms.

Front

What does VSEPR stand for?

Back

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

Front

What is the shape of a molecule with 2 bonding pairs and 0 lone pairs?

Back

The shape of a molecule with 2 bonding pairs and 0 lone pairs is linear.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is the significance of lone pairs in VSEPR theory?

Back

Lone pairs of electrons can affect the shape of a molecule by repelling bonding pairs, leading to different molecular geometries.

Front

What is the molecular shape of a molecule with 4 bonding pairs and 0 lone pairs?

Back

The molecular shape of a molecule with 4 bonding pairs and 0 lone pairs is tetrahedral.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, while nonpolar covalent bonds occur when electrons are shared equally.
