Bonding, Molecular Geometry & Formula writing

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 (highest) energy level of an
atom.

Question 3

Valency:

Answer 3

the number of electrons gained, 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

Non-polar covalent (pure covalent):

Question 6

Polar covalent:

Answer 6

is an unequal sharing of electrons leading to a dipole forming (as a
result of electronegativity difference)

Question 7

Electronegativity:

Answer 7

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

Question 8

Ionic bond:

Answer 8

is a transfer of electrons and subsequent electrostatic attraction.

Question 9

Metallic bonding:

Answer 9

is the bond between a positive kernel and a sea of delocalised
electrons.

Question 10

Bond Energy:

Answer 10

the amount of energy needed to break a specific bond.
