Bonding Unit regents chemistry

___________ a molecule containing two “poles,” or regions of opposite charge.

• Dipole

• Polarity

• Nonpolar

• North Pole

An intermolecular force of attraction

between two polar molecules.

• Dipole-dipole

• London Dispersion Forces

• Hydrogen Bonding

• Ionic

___________ a measure of how strongly one atom attracts a shared pair of

electrons. Values range from 0.7 to 4.0, and are unitless.

• Electronegativity

• Intermolecular froces

• Intramolecular forces

• Polarity

Which of the following statements is FALSE?

• Elements are made up of 1 type of atom.

• Elements cannot be broken down chemically.

• Atoms of the same element can have different amounts of protons.

• Atoms of the same element can have different amounts of neutrons.

_____________ – a bond characterized by equal sharing of electrons. The atoms in a bond have the same electronegativity (or a difference less than

or equal to 0.4).

• Nonpolar Covalent

• Polar Covalent

• Ionic

• Metallic

__________ a bond formed by the attraction between two oppositely charged ions. These are the most polar type of bond since valence electrons are

completely transferred from one atom to another. These bonds occur if the electronegativity difference is greater than/equal to 1.67.

• Ionic

• Polar Covalent

• Nonpolar Covalent

• Metallic

Dipole-Dipole forces are stronger than _______ and weaker than _________ interactions.

• london dispersion, ion-dipole

• hydrogen bonding, london dispersion

• ion-dipole, london dispersion
