Solution and Explanation
In sheet silicates, three oxygen atoms of each tetrahedra are shared with adjacent $SiO_{4}^{4-}$ tetrahedra. In chain silicates, two oxygen atoms are shared by each tetrahedra.
Double-chain silicates occur when tetrahedra form a double chain by sharing two or three oxygen atoms. In $3D$ silicates, each tetrahedra shares all the four oxygen atoms with its neighbours.
P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
