Bonding, Molecular Geometry & Intermolecular Forces

Question 1

Electronegativity

Answer 1

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

Question 2

Intramolecular bond

Answer 2

A bond which occurs between atoms within molecules.

Question 3

Ionic bond

Answer 3

Transfer of electrons and subsequent electrostatic attraction.

Question 4

Covalent bond

Answer 4

Sharing of at least one pair of electrons by two non-metal atoms.

Question 5

Pure/non-polar covalent bond

Answer 5

An equal sharing of electrons.

Question 6

Polar covalent bond

Answer 6

Unequal sharing of electrons leading to a dipole forming as a result of a difference in electronegativity between the atoms.

Question 7

Metallic bonding

Answer 7

The bond between a positive kernel and a sea of delocalised electrons.

Question 8

Intermolecular force

Answer 8

A weak force of attraction between molecules, ions, or atoms of noble gases.

Question 9

Kinetic energy

Answer 9

The energy an object has as a result of the object’s motion.

Question 10

Kinetic-Molecular theory

Answer 10

All matter consists of small particles which move continuously. Temperature is a measure of the average kinetic energy of the particles of which matter consists.
