c) Na+ and Cl
d) Na+ and CL-

4. Electrostatic force is produced due to?

a) two oppositely charged ions"
b) two bodies with similar charge
c) all are correct

5. Chemical bond is a force of attraction between atoms which hold them together in the form of a?

a) Molecule or a compound Ions
b) no one is correct
c) Mixture

6. Define ionic bond?

a) A bond formed due to electrostatic force of attraction between oppositely charged ions. It is also called electrovalent bond.
b) A bond formed due to electromegnatic force of attraction between oppositely charged ions. It is also called electrovalent bond.

7. Define Covalent Bond?

a) It is the force of attraction that arises between three atoms due to mutual sharing of an electron pair.
b) It is the force of attraction that arises between two atoms due to mutual sharing of an electron pair.

8. Define Coordinate Covalent Bond?

a) When the shared pair of electrons is provided by one of the bonded atoms, a coordinate covalent bond is formed.
b) When a pair of electrons is provided by one of the bonded atoms, a coordinate covalent bond is formed.

9. Define Metallic Bond?

a) When negaitively charged metal ions are held together by freely moving electrons, the bond formed is called a metallic bond.
b) When positively charged metal ions are held together by freely moving electrons, the bond formed is called a metallic bond.

10. Covalent Bond is the force of attraction that arises between two atoms due to mutual sharing of an electron pair.

a) False
b) True
