Back (Answer)

SO4 2- OH - NO3 - CO3 2- NH4 +

#15

Front (Question)

Define dative covalent bond

Back (Answer)

covalent bond formed by one atom donating its lone pair of electrons to another atom

#16

Front (Question)

Metallic bonding

Back (Answer)

attraction between delocalised electrons and positive ions arranged in a lattice

#17

Front (Question)

4 types of crystal structure

Back (Answer)

ionic metallic macromolecular (giant covalent) molecular

#18

Front (Question)

Why do pairs of electrons in the outer shell of atoms arrange themselves as far apart as possible

Back (Answer)

To minimise repulsion

#19

Front (Question)

Lone pair–lone pair repulsion is _____ than lone pair–bond pair repulsion, which is _____ than bond pair–bond pair repulsion

Back (Answer)

Greater Greater

#20

Front (Question)

Define electronegativity

Back (Answer)

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

#21

Front (Question)

Ionic crystal structure properties, using sodium chloride as an example

Back (Answer)

-strong electrostatic forces of attraction between oppositely charged ions in a giant lattice -high melting point -can conduct electricity when molten or aqueous, as not in lattice -brittle, as like charges repel when layers of alternating charges are distorted -breaks lattice into fragments

#22

Front (Question)

Metallic crystal structure properties, using aluminium as an example

Back (Answer)

-strong electrostatic forces of attraction between positive nucleus and sea of delocalised electrons in a giant lattice -hence high melting point -malleable as layers can slide over each other -good conductors as sea of delocalised electrons can carry a flow of charge

#23

Front (Question)

Simple molecular crystal structure properties, using iodine as an example

Back (Answer)

-covalently bonded -held together by weak Van der Waals between molecules -low melting and boiling points -poor conductors as no charged particles

#24

Front (Question)

Macromolecular crystal structure properties, using diamond and graphite as examples

Back (Answer)

-rigid due to strength of giant lattice -very high melting point as each atom has multiple covalent bonds -sometimes has flat sheets which has delocalised electrons, hence can conduct electricity
