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.

Dioxide

  • The dioxide is generally represented by O2, consisting of two oxygen atoms.
  • One oxygen atom is having atomic number 8 having electronic configuration 1s22s22p4.
  • When two oxygen atoms combine with each other then due to shared pair of electrons it shared zero valency.

Hence the valency of dioxide is 0.
