Solution

Valency

  • The valency of an atom refers to its ability to combine with other atoms.
  • The valency of an element determines the number of bonds that an atom can make as part of a complex.
  • The electrons in the atom's outermost orbit are referred to as valence electrons.

Valency Of Carbon

  • An element's valency is a measure of its ability to combine with other atoms to form chemical compounds or molecules.
  • Carbon's electronic configuration (C=6) is 1s22s22p2.
  • Carbon's valency is determined by the following factors:
  • Carbon either gets four electrons or loses four electrons to complete the octet structure.
  • As the carbon atom is so small, it would be difficult for the nucleus to hold four additional electrons if it gained electrons.
  • It takes a lot of energy to remove four electrons from the nucleus when carbon loses its electrons.
  • By sharing its valence electrons, carbon forms four covalent bonds and achieves the noble gas structure.

Hence carbon will show the valency of 4.
