3. METAL AND NON METAL
WHAT IS METAL AND NON METAL……..??
A metal is a solid
material
(an element, compound,
or alloy). 91 of the 118
elements in the periodic

4. METALLIC BOUND
Metals are crystalline solid
and atoms are linked to
one another by special
types of bonds known as
metallic bond.
Two parts of metallic bond-
a) Valence electron.

5. PHYSICAL PROPERTIES OF METAL :::---
Metallic Lustre (shine or
brightness)- gold and platnium ,
exception- aluminium, copper
and silver.
 Hardness- silver and copper
exception – sodium magnesium
Melting and boiling point –(atom
are closely packed) exception -

6. Density (crystalline in nature) –
iron is 7.86 g cm , nickel
is 8.9 g cm.
Malleability -the property due
to which metal can be
beaten into sheets. Eg- Silver
and aluminium.
Ductility –The property due to
which a metal can be drawn

7. Thermal conductivity (heat) –
thermal conductivity of metal
is because of the movement
of kernels and valence
electron. Eg-silver and copper
. Exception lead and
mercury.
Sonorosity (sound) – all metal
are sonorous in nature.

8. In chemistry, a nonmetal or
non-metal is a chemical
element which mostly
lacks metallic attributes.
Non metal s form a large
number of compound which are
extremely useful.
For example – ammonia, nitric ,

9. Seventeen elements are
generally classified
as nonmetals; most are
gases (hydrogen, helium,
nitrogen, oxygen,
fluorine, neon, chlorine,
argon, krypton, xenon

12. CHEMICAL PROPERTIES OF METAL AND NON
METAL
Metal
Metal + oxygen =metal
oxide Example-4 Na+
O2=2Na2O
2Mg +O2 =2MgOException – silver and

13. NATURE OF METAL OXIDES
a) Action with water.
Metal oxide + water
= hydroxide(alkali)
Na2O + H2O =
2NaOH
b) Action with acid.
Metal oxide+ acid =
salt + water

14. Reaction
with hydrogen
Metal + hydrogen = metal
hydrides
2Na (s) + H2 = 2NaH(s)
Metal hydrides + water =
hydrogen gas + hydroxide
NaH(s) + H2O (l) = NaOH(aq)
+ H2(g)
Reaction with

15. Reaction with acid
Metal + acid = metal salt
+ hydrogen
2Na (s) + 2HCl = 2NaCl(aq)
+ H2
Reaction of metal
with the solution of

16. Non – metal + oxygen = oxides
Examples- C(s) + O2(g) = CO2
 S8(s) + 8O2 = 8SO2

17. Non-metal + acid = oxide +water
examples –
S+2H2SO4(conc.)=3SO4+2H2O
S+6HNO3=H2SO4+6N3+H2O
Non –metal + chlorine= chlorides
example- 2P + 5CL2=2PCL5
2S + CL2=S2CL2

18. Non – metal+hydrogen=hydrides
examples-
H2(g)+ S (s)=H2S
N2(g)+3H2(g)=2NH3(g)
