What type of bond would you expect for (a) the N2 molecule, (b) the HCl molecule, (c) Fe atoms in a solid?
(a)
Find the type of bond present in N2 molecule.
Answer to Problem 1Q
The type of bond present in N2 molecule is covalent.
Explanation of Solution
The nitrogen molecule is diatomic molecule and has five valence electrons so it needs three more valence electron to complete its octet.
Thus the nitrogen molecule will share its three electron with another nitrogen to form octet so the bonding in nitrogen molecule is covalent.
(b)
Find the type of bond present in HCl molecule.
Answer to Problem 1Q
The type of bond present in HCl molecule is ionic.
Explanation of Solution
The HCl molecule is diatomic molecule and when it is bubbled into water it ionizes completely as hydrogen ion and chlorine ion.
Even in the gases state of HCl, chlorine is partially negative and hydrogen is partially positive thus the bond in the HCl is ionic.
(c)
Find the type of bond present in Fe atom in solid.
Answer to Problem 1Q
The type of bond present in Fe atom in solid is metallic.
Explanation of Solution
The Fe atom are metal and when it present in the solid state form they form metallic bond with another metal atoms.
Thus the bonding in Fe atom in metal is metallic.

- The Madelung constant for the NaCl structure may be found by summing an infinite alternating series of terms giving the electrostatic potential energy between an Na+ ion and its 6 nearest Cl neighbors, its 12 next-nearest N+ neighbors, and so on (see Fig. 12.1a). (a) From this expression, show that the first three terms of the infinite series for the Madelung constant for the NaCl structure yield = 2.13. (b) Does this infinite series converge rapidly?
