Chemical Bonding

Question 1

Intramolecular Bond

Answer 1

Is A bond which occurs between atoms within molecules

Question 2

Valence electrons

Answer 2

The electrons found in the outermost energy level of an atom

Question 3

Valency

Answer 3

The number of electrons gain lost or shared to complete the outermost energy level

Question 4

Covalent bond

Answer 4

Is a sharing of at least one pair of electrons by two non-metal atoms

Question 5

Non polar covalent (pure covalent)

Answer 5

Is an equal sharing of electrons

Question 6

Electronegativity

Answer 6

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

Question 7

Ionic bond

Answer 7

Is the transfer of electrons and subsequent electrostatic attraction

Question 8

Metallic bond

Answer 8

Is the bond between a positive kernel and a sea of the delocalised electrons

Question 9

Bond energy

Answer 9

The amount of energy needed to break a specific bond

Question 10

Kinetic energy

Answer 10

The energy an object has as a result of the objects motin

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

Question 12

Intermolecular force

Answer 12

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

Question 13

Molar mass

Answer 13

Mass in grams of one mole of that substance

Question 14

Polar covalent

Answer 14

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