The trends, in melting points of the elements of the 3rd period, are depicted in the figure below.
The sharp decrease observed from ‘Si’ to ‘P’ is due to
- A
Decrease in atomic radius from ‘Si’ to ‘P’
- B
Change in bonding and structure of two elements
- C
Different universities of two elements
- D
Increase in electron density from ‘Si’ to ‘P’
From Si onwards, the bonding and structure of the element change from covalent to weak van der Waal forces that cause the decrease in melting point, as shown in the diagram.
Options A, C, D: As explained above, they are incorrect options
