Bonding & Intermolecular Forces

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

Unequal sharing of electrons leading to a dipole forming. This is the 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 objects 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
