Title: Prediction of formation of ionic and covalent substances


1
Prediction of formation of ionic and covalent
substances
2
Integrated Chemistry Today
  • Book 1A, 2nd EditionSummary(pg 95-96)

3
Different substances (Pg 96)
4
Reaction between metal and non-metal
Formation of ionic bond
5
Reaction between non-metal and non-metal
Formation of covalent bond
6
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.

7
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

10
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

11
Q 10 (pg 99)
  • Draw diagrams to show the structures of sodium
    chloride and quartz.

quartz
sodium chloride

Q 21 (pg 101)
  • Study each of the following sets of substances.
    Pick the odd one out. Give a reason of your
    choice in each case.a) sodium sulphate, calcium
    chloride, tetrachloromethane, lead(II)
    bromide.b) water, quartz, carbon dioxide,
    ammonia

14
Q 21 (pg 101)
  • a) sodium sulphate, calcium chloride,
    tetrachloromethane, lead(II) bromide.

15
Q 21 (pg 101)
  • a) sodium sulphate, calcium chloride,
    tetrachloromethane, lead(II) bromide.Tetrachloro
    methane is the only covalent compound. All others
    are ionic compounds.

16
Q 21 (pg 101)
  • b) water, quartz, carbon dioxide, ammonia

17
Q 21 (pg 101)
  • b) water, quartz, carbon dioxide, ammoniaQuartz
    is the only one with giant covalent structure.
    All others have simple molecular structure.

18

    formed when each of the following pairs of
    elements react together. Draw electron diagrams
    for the compound formed.a) Phosphorus and
    hydrogenb) Calcium and fluorinec) Sodium and
    hydrogend) Potassium and oxygene) Sulphur and
    chlorine

Q 23 (pg 101)
P is potassium chloride Q is copper R is
copper(II) bromide S is sugar
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.
