Chapter 1, Problem 7RQ Problem Describe covalent bonding in silicon. Step-by-step solution Step 1 of 3 Covalent bonding is the bonding which is resulted due to the sharing of electrons between atoms. The shared electrons fill valence energy shell of each atom. Step 2 of 3 The element silicon is found in group IV of the periodic table. It has four valence electrons and to complete the valence energy shell, it needs four more electrons. Draw the diagram that describes the covalent bonding between the silicon atoms. Si Si Si Si Si Step 3 of 3 As shown in the diagram, if a silicon atom has four nearest neighbors and each neighbor atom shares one valence electron, then this sharing results in the center atom to have eight electrons in its outer shell. The diagram shows the five non-interacting silicon atoms which share atoms to fill the valence energy shell of the center atoms. Similarly, the covalent bonding also results in the formation of the silicon crystal. Thus, the above explanation describes the covalent bonding in silicon.
