Chemical Bonding

Elements consist of one type of atom only, most of the elements
we can find in our everyday life. E.g. Copper, Iron, Oxygen,
Nitrogen and Aluminum.
Compounds are chemically bonded they are formed by two
elements or more chemically reacting together. Compounds are
difficult to separate back to…

Group 1 and 2 elements lose electrons to form positive ions which are
also called cations.
Group 6 and 7 elements gain electrons to form negative ions which are
also called anions.


Giant Ionic structures:
Ionic bonds always produce ionic structures, because the ions form
closely packed regular lattice arrangement.…

The atoms are bonded together by strong covalent bonds.
They have high boiling and melting points.
They don't conduct electricity
They're usually insoluble in water

Metallic bonding:
The outer electrons in each atom can easily move from one atom to the
next. So, the outer electrons form a `sea' of…
