Question

Give one example of polyvalent monoatomic anion.

Answer 1

Polyvalent monoatomic Anion

• Negatively charged, atom or radicle with variable valency and with atomicity of one
• An example for polyvalent monoatomic anion is ${\mathrm{O}}^{-2},{\mathrm{O}}^{-}$etc. here oxygen has the ability to show variable valency of -1 in ${\mathrm{H}}_2{\mathrm{O}}_2$and valency of -2 in ${\mathrm{H}}_2\mathrm{O}$
