chapter 3

Question 1

ionic bonding

Answer 1

ion arranged in a giant ionic lattice

Question 2

covalent bond

Answer 2

pair of electrons shared between the atom bonding together

Question 3

dative covalent bond

Answer 3

covalent bond that forms when both of the bonding electrons are provided by the same atom

Question 3

Macromolecular compounds

Answer 3

atom join together by many strong covalent bonds in a giant lattice

Question 4

Metallic Bonding

Answer 4

strong electrostatic attraction that occurs between delocalized outer shell electrons and positive metal ions

Question 5

electronegativity

Answer 5

the ability of an atom to attract a pair of electrons in a covalent bond

Question 6

non-polar bonds

Answer 6

occurs when atoms have equal electronegativities so electrons are equally attracted to both nuclei

Question 7

polar bonds

Answer 7

covalent bonds are polarised by differences in electronegativity

Question 8

intermolecular force

Answer 8

• van der waals
• permanent dipole
• hydrogen bond

Question 9

van der waals

Answer 9

happens in all chemical

Question 10

permanent dipole

Answer 10

the attraction between polar molecules only

Question 11

hydrogen bond

Answer 11

• strongest intermolecular force
• H bond with N, O, F only
