2. CHEMICAL BONDING
Group 5

3. Who proposed the chemical bonds?
GILBERT NEWTON LEWIS
- an American chemist who
proposed that the chemical bonds
are formed between atoms
because electrons from the atoms
interacts with each other.

4. GILBERT NEWTON LEWIS
- observed that many elements are most
stable when they contained eight electrons in
their valence shell like that of the noble
gases
- condition is attained by atoms either by
transferring or sharing electrons
- two processes of forming the two main
types of chemical bonding: ionic and
covalent bonding

5. IONIC BONDING
It involves the combination of ions of opposite
charges

6. - are positively-charged atoms which are formed
when an atom loses electrons. The charge depends
on the number of electrons the atom lost

7. - are negatively-charged atom which are formed when
an atom gains electrons. The charge depends on the
numbers of electron the atom gained.

8. NaCl
a positively-charged Sodium ion (left) and a
negatively-charged Chlorine ion (right)

9. Sodium
Metal
+
Chlorine
gas
Table salt
Sodium Metal – is a very reactive metal. It
reacts violently and it produces flame once
it gets wet.
Chlorine – is a poisonous gas used as
a weapon in World War I.

10. The compounds formed are called ionic compounds.
After the reaction takes place, the
+ and Cl- ions are held
charged Na
together by electrostatic forces, thus
forming an ionic bond.

11. FEATURES OF IONIC COMPOUNDS
• Ionic compounds form between metals
and naming simple ionic compounds, the
• In non-metals.
metal is always given first, the non-metal
(i.e., Sodium chloride)
• Ionic compounds dissolve easily in water
and other polar solvents.
• In solutions, ionic compounds easily
conduct electricity.
• Ionic compounds tend to form crystalline
solids with high melting temperature.
