▪️Find the Valency of the constituent atoms of NaOH.

✏️$\huge\red{\underline{{\bf Answer : }}}$

▪️The valency number of NaOH is 1.

▪️The term valency refers to the number of the electron which is involved in the formation of the bond between two elements.

▪️To find the valency of a compound, its constituent elements must be identified.

▪️In the case of NaOH, it is composed of ion and ion.

Find the Valency of the constituent atoms of Mg.

✏️$\huge\red{\underline{{\bf Answer : }}}$

▪️So, say oxidation state of Mg is 'x'. so, For polyatomic substances, total O.S. of polyatomic molecule is equal to sum of O.S. of its constituent ions formed from bond fission.

▪️So, valency of Mg is +2.

Find the Valency of the constituent atoms of the following compounds.

NaOH.

$\huge\red{\mid{\underline{\overline{\textbf{Ꮧɴʂաᴇʀ᭄࿐:-}}}\mid}}$

To find the valency of a compound, its constituent elements must be identified.

• ⇝ In the case of NaOH, it is composed of ion and ion.
• ⇝It means that for the formation of NaOH, sodium loses one electron and combines with hydroxide ion.
• ⇝As the overall net charge of NaOH is 1,
• ⇝its valency is identified as 1
