(a)
Interpretation:
The total number of valence electrons in COCl2 should be determined.
Concept Introduction:
Valence electrons are the electrons present in the outermost orbital or shell of an atom which participates in the formation of bond with another atom.
The bonds formed between two atoms by sharing of electrons are known as covalent bond. A single
Total number of valence electron for a molecule can be determined by adding all the electrons present in the outermost shell of each atom present in a molecule such as:
For HxOy
Total number of valence electrons = number of H atoms (valence electron of H) + number of O atoms (valence electron of O)
Or,
Moreover, if the given species is an ion, 1 electron is added to the total number of valence electrons for a negative charged ion and 1 electron is subtracted from the total number of valence electrons for a positive charged ion.
(b)
Interpretation:
The total number of valence electrons in N2O should be calculated.
Concept Introduction:
Valence electrons are the electrons present in the outermost orbital or shell of an atom which participates in the formation of bond with another atom.
The bonds formed between two atoms by sharing of electrons are known as covalent bond. A single chemical bond is formed by sharing of 2 electrons while double bond is formed by sharing of 4 and triple bond is formed by sharing of 6 electrons.
Total number of valence electron for a molecule can be determined by adding all the electrons present in the outermost shell of each atom present in a molecule such as:

Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur).
