State the valency of nitrate

Content Curator

The valency of nitrate can be calculated by determining the number of electrons that are involved in chemical bonding in the nitrate ion. This is determined by considering the chemical formula of nitrate, which is NO3-, and determining the number of electrons in the ion.

Valency of Nitrate

Valency of Nitrate

Step 1: Determine the number of electrons in the ion. The nitrate ion has a charge of -1, which means that it has gained one electron.
Step 2: Determine the number of valence electrons in nitrate. The nitrate ion consists of nitrogen (N) and oxygen (O) atoms, and it is possible to determine the number of valence electrons for each of these atoms by examining their electron configurations. Nitrogen has five valence electrons, and oxygen has six.
Step 3: Calculate the total number of valence electrons. The total number of valence electrons in the nitrate ion is 5 + 6 x 3 = 23, since there are three oxygen atoms in the ion.
Step 4: Calculate the valency of nitrate. The valency of nitrate can be calculated by subtracting the number of valence electrons from the number of electrons in the ion. In this case, the valency of nitrate is 1 - 23 = -22.

So, the valency of nitrate is -22, meaning that it has 22 electrons involved in chemical bonding.
