This document discusses the different types of chemical bonds: ionic bonds form between metals and nonmetals through the transfer of electrons from the metal to the nonmetal; covalent bonds involve the sharing of electron pairs between nonmetals to form molecules like CO2 and N2; coordinate bonds are similar to covalent bonds but involve one atom donating an electron pair; and hydrogen bonds occur when hydrogen atoms are attracted to slightly negative atoms like oxygen, as seen in water molecules. The document provides examples and brief explanations of each bond type.

2. WHAT IS THE BOND?
 BOND: IS AN ATTRACTION BETWEEN ATOMS THAT
FORMS CHEMICAL SUBSTANCES.
 Chemical bonds are the forces that hold together in the
molecules forming the compounds

3. TYPES OF BONDS :
 IONIC BONDS:
 Ionic bonds occurs between
metal and non metal.
 In the ionic bond there is
complete transfer of electrons
from the metal giving cation to
nonmetal giving anion

4. cont.
COVALET BOND :
in covalent bonding non
metals share electrons .
There can be double bonds
in CO2 ,and triple bonds in
N2 .

5. Cont.:
 Co-ordinate bond:
 This is similar to covalent
bond, but the shared pair
of electrons is donated by
the partner atom.

6. Cont.:
 HYDROGEN BONDS:
 This can be illustrated in
water molecule.
 The molecular formula of
water is H2O, the oxygen
is more negative than
hydrogen.
