Bond & Molecule Polarity

Front

What is a polar bond?

Back

A bond with a partially negative end and a partially positive end due to unequal sharing of electrons.

Front

What type of molecule is formed when the molecular structure is symmetrical?

Back

Nonpolar molecule.

Front

What determines if a bond is polar or nonpolar?

Back

The difference in electronegativity between the two atoms involved in the bond.

Front

In a polar covalent bond, where do the electrons spend more time?

Back

Around the atom with the greatest electronegativity.

Front

What is the characteristic of a nonpolar molecule?

Back

It has an even distribution of charge and is symmetrical.

Front

What type of bond is formed when there is a complete transfer of electrons?

Back

Ionic bond.

Front

What is electronegativity?

Back

The ability of an atom to attract electrons in a bond.

Front

How can you identify a polar molecule?

Back

By checking if it has a net dipole moment due to an asymmetrical distribution of charge.

Front

What is the result of a bond between two atoms with similar electronegativities?

Back

A nonpolar covalent bond.

Front

What happens to the electrons in an ionic bond?

Back

They are transferred from one atom to another.
