Solution

Covalency

  • Covalency refers to the number of electron pairs that an atom shares with one or more atoms of the same or other types in order to have a stable electronic configuration.
  • Atom has a covalency of 1 if it can share one electron.
  • Atom has a covalency of 2 if it can share two electrons.

Maximum covalency of first elements of each group

  • The maximum covalency of an element is the number of covalent bonds that an atom of that element may establish with neighboring atoms.
  • The maximum covalency of an element is equal to its group number.
  • The maximum covalency of each group's first elements is 4.
  • Due to the small atomic size, the lack of vacant d-orbitals, and the extremely electronegative character.

Examples

  • Group 14, the first element Carbon C, shows a maximum covalency of four.
  • Group 15, the first element Nitrogen N, also shows maximum covalency of four.
