Electronegativity and Bond Polarity

Front

What does the symbol δ represent in chemistry?

Back

The symbol δ (lowercase delta) indicates a partial positive or partial negative charge.

Front

What does the direction of the dipole arrow indicate in a bond?

Back

The direction of the dipole arrow indicates which atom is more electronegative in the bond.

Front

In a Lewis structure, what does a symbol above an atom signify?

Back

It signifies the relative attraction of electrons to that atom compared to others in the structure.

Front

What type of bond is present in the molecule H2?

Back

The bond in H2 is a nonpolar covalent bond.

Front

How is the bond between cesium (Cs) and bromine (Br) classified?

Back

The bond between Cs and Br is best classified as ionic.

Front

Define electronegativity.

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

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, resulting in partial charges.

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 an ionic bond?

Back

An ionic bond is a type of bond formed when one atom transfers electrons to another, resulting in oppositely charged ions.

Front

What is the significance of the dipole moment in a molecule?

Back

The dipole moment indicates the polarity of a molecule and the distribution of electrical charge.
