Name the structure of silicates in which three oxygen atoms of $[SiO_4]^{4-}$ are shared is
- pyrosilicate
- sheet silicate
- linear chain silicate
- three-dimensional silicate
The Correct Option is B
Approach Solution - 1
Approach Solution -2
Two dimensional sheet silicates: In such silicates, three oxygen atoms of each tetrahedral are shared with adjacent \(SiO_4^{4-}\) tetrahedral, such sharing forms two dimensional sheet structure with general formula \((Si_2O_5)_n^{2n-}\)
Ex. Talc \(Mg(Si_2O_5)_2Mg(OH)_2\)
The structure of silicates has been found with the help of X-ray diffraction techniques.
Hence, The correct Answer is option B sheet silicate.

P-Block Elements
- 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.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
