Electronegativity and polar bonds

Which atom is the most electronegative?

• H

• N

• O

Electronegativity is the ability of an atom to

• Repel electrons

• Repel protons

• Attract electrons

• Attract protons

Which atom is the most electronegative?

• I

• Br

• Cl

• F

• Li

• B

• N

• F

Which atom is the most electronegative?

• Na

• Si

• S

• Cl

Which atom is the most electronegative?

• C

• Si

• H

In a C-O bond the electrons are

• Pulled towards the O

• Pulled towards the C

• Are spread equally between the C and O

In the C-Cl bond electrons are

• Pulled towards the C

• Pulled towards the Cl

• Shared equally between the C and Cl

A polar bond is when

• Electrons are shared equally.

• Electrons are shared unevenly and are mostly around one of the atoms in the bond.

A bond dipole is when there is a

• Polar bond

• Non-polar bond

• A polar molecule

• A non-polar molecule.
