6. Bond polarity + electronegativity

page 5 on packet

What is electronegativity?

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

What is the electronegativity trend?

F>O>N>Cl>Br (up into the right)

What does polar mean?

Something that has an uneven distribution of electrical charge (one side is positive, one is negative)

What is a dipole moment?

electrons are shared unevenly in a compound, chemists use an arrow to show the direction in which the electrons are being pulled (mu unit)

What is a polar-covalent bond?

Covalent bond in which electrons are not shared equally, resulting in a net dipole
moment (μ)

What is a NON-polar covalent bond?

Covalent bond in which electrons are shared relatively equally

What is a ionic bond?

when electrons transfer from one atom to another
