3.0 Bonding Aqa Alevel chemistry

Ionic bonding occurs between a ?

metal and a non-metal

In Ionic bonding Electrons are transferred from the
[x] to the [Y] to achieve full outer shells.

X.metal , Y.non-metal

In ionic bonding When the electrons are transferred, it creates charged particles called ?

ions

Oppositely
charged ions attract through electrostatic forces to form a _____ _______ ____?

giant ionic lattice.

What is the name of the common compound SO4
2-

+

Ammonium

Covalent bonds form between two what ?

non-metals

In covalent bonds Electrons are shared between the [x] outer
shells in order to achieve a [y] outer shell

x.two y.full

[x] electron pairs can be shared to produce
[x] covalent bonds.

Multiple

Dative or coordinate bonds form when both of the electrons in the shared pair are supplied
from a _____ ____

Single atom

what type of bonding consists of a lattice of positively charged ions surrounded by a ‘sea’ of
delocalised electrons

Metallic

True or false: in metallic bonding a very strong electrostatic force of attraction is had between
oppositely charged particles

True

The greater the charge on the positive metal ion the [A] the attractive force as more [B] are released into the sea

a=stronger b=electrons

Physical properties of a substance include ...

boiling point, melting point, solubility and
conductivity

4 types of crystal structure
