When atoms react to form chemical bonds, only the electrons in the outermost or
valence shell are involved. Thus, the configuration of the valence shell is important
in bond formation. In order to place emphasis on the electrons in the outermost shell,
a special symbol known as Lewis diagram (also called electron-dot structures) is used.
Assuming that, element P has seven electrons, while element Q has eight electrons.
When element P shared electrons with element Q, it will form an anion.
Illustrate a 'dot and cross' diagram to show the bonding between element P and
element Q.
Based on the diagram, indicate the shape and the angle bond. Explain your answer.
The enthalpy change for the reaction between two molecules of carbon oxysulfide (COS) to form one molecule of CO2 and one molecule of CS2, as shown below, is –3.2 × 10–24 kJ per molecule of COS. The bond energy for the C=S bond in CS2 has been determined to be 552 kJ/mol.
What is the apparent bond energy of a carbon–sulfur bond in COS? Use the bond energies below.

- In chemical reactions, heat is converted into chemical energy (the potential energy stored in chemical bonds) or vice versa. Bond energy is the energy required to break one mole of the bond in the gas phase. Since it takes energy to break a bond, bond energies are always positive. Conversely, energy is released when bonds are formed.
