Bonding and IMF

Question 1

Molar mass

Answer 1

Mass in grams of one mole of that substance.

Question 2

Electronegativity

Answer 2

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

Question 3

Intramolecular bond

Answer 3

A bond which occurs between atoms within molecules.

Question 4

Ionic bond

Answer 4

– Transfer of electrons and subsequent electrostatic attraction.

Question 5

Covalent bond

Answer 5

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

Question 6

Non-polar covalent bond (Pure covalent)

Answer 6

An equal sharing of electrons.

Question 7

Polar covalent bond –

Answer 7

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

Question 8

Metallic bonding

Answer 8

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

Question 9

Intermolecular force

Answer 9

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

Question 10

Kinetic energy

Answer 10

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

Question 11

Kinetic-Molecular theory

Answer 11

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.
