1st - Covalent Formulas, Naming, and Electronegativity

Front

What is a covalent bond?

Back

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

Front

Define electronegativity.

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What is the Lewis dot structure?

Back

The Lewis dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

How do you determine the polarity of a bond?

Back

The polarity of a bond is determined by the difference in electronegativity between the two atoms involved.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of bond where electrons are shared equally between two atoms.

Front

What is the formula for oxygen dichloride?

Back

The formula for oxygen dichloride is OCl₂.

Front

What is the significance of the electronegativity difference in determining bond type?

Back

The electronegativity difference helps to classify bonds as nonpolar covalent (0-0.4), polar covalent (0.5-1.7), or ionic (1.8 and above).

What is the polarity of H-Cl?

Back

H-Cl is a polar molecule.

Front

What is the polarity of C-H?

Back

C-H is a nonpolar bond.
