Reaction betweenmetal and metal

• Metal atom does not react with metal atom.
• They just mix together and metallic bond forms
  among the atoms.
• The nature of metallic bond will be studied later.

Q 1 (pg 97)

• Explain the following terms a) ionic bond b)
  covalent bondc) lone pair

8
Q 1 (pg 97)

• Explain the following terms a) ionic bond - an
  electrostatic attraction exists among oppositely
  charged ions b) covalent bondc) lone pair

9
Q 1 (pg 97)

• Explain the following terms a) ionic bond - an
  electrostatic attraction exists among oppositely
  charged ions b) covalent bond- an electrostatic
  attraction formed by sharing of electron between
  2 non-metal atomsc) lone pair

Q 1 (pg 97)

• Explain the following terms a) ionic bond - an
  electrostatic attraction exists among oppositely
  charged ions b) covalent bond- an electrostatic
  attraction formed by sharing of electron between
  2 non-metal atomsc) lone pair- outermost
  electron pair not involved in covalent bond
  formation

26
Q 23 (pg 101)
P is potassium chloride Q is copper R is
copper(II) bromide S is sugar The bonding in P is
ionic bonding.
27
Q 23 (pg 101)
P is potassium chloride Q is copper R is
copper(II) bromide S is sugar The bonding in P is
ionic bonding. In solid state, the ions present
are held in fixed position by strong ionic bond
while in molten state, they are free to move to
conduct electricity.
