IMF Definitions

Question 1

Molar mass

Answer 1

The mass in grams of one mole of that substance

Question 2

Electronegativity

Answer 2

The 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 electron pair by two non-metal atoms

Question 6

Pure covalent bond

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 its motion
