This document discusses the properties and chemical reactions of metals and non-metals. It defines metals as solid materials that form metallic bonds between closely packed atoms. Metals have properties like lustre, malleability, and conductivity. Non-metals lack metallic properties and form many useful compounds. The document outlines common chemical reactions of metals, such as forming oxides with oxygen or salts with acids, and reactions of non-metals like combining with oxygen to form oxides or chlorine to form chlorides. In conclusion, it thanks the reader for their time.

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)
