Unit 7: Covalent Bonds

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two nonmetal atoms share one or more pairs of electrons.

Front

What type of covalent bond is the strongest?

Back

Triple bond.

Front

What is the bond angle of a bent VSEPR shape?

Back

104.5 degrees.

Front

What two types of atoms make a covalent bond?

Back

Nonmetal and nonmetal.

Front

What is a resonance structure?

Back

A resonance structure represents electron pairs resonating back and forth between the structures.

Front

If a molecule has a tetrahedral VSEPR shape, what is its bond angle?

Back

109.5 degrees.

Front

What is the difference between a single, double, and triple bond?

Back

A single bond involves one pair of shared electrons, a double bond involves two pairs, and a triple bond involves three pairs.

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 the significance of bond angles in molecular geometry?

Back

Bond angles determine the shape of the molecule, which affects its reactivity and properties.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two nonmetals, resulting in a molecule with a slight charge.
