3. Polarity (Electronegativity Difference)

Question 1

Define electronegativity.

Answer 1

the term used to measure the tendency of an atom to attract a bonding pair of electrons.

Question 2

what is a non-polar bond?

Answer 2

it is an equal sharing of electrons between atoms. Also known as a pure covalent bond.

Question 3

True or false, there is a electronegativity difference between atoms of the same element.

Answer 3

False, there is no electronegativity difference between atoms of the same element and atoms attract the shared electrons equally.

Question 4

What is an polar bond?

Answer 4

an unequal sharing of electrons leading to a dipole forming; as a result of an electronegativity difference.

Question 5

Does a polar bond change the overall charge on a molecule?

Answer 5

No, the overall charge on the molecule is neutral. However the atoms are polarised or attracted to one side of the molecule.

Question 6

Where does the electron pair get attracted to?

Answer 6

it is pulled more toward the atom with the higher electronegativity.
