Calculate the effective atomic no. of Pt in` [Pt(Cl)_6]^(2-)`

Explanation

To calculate the effective atomic number (EAN) of platinum in the complex ion \([Pt(Cl)_6]^{2-}\), we can follow these steps:

### Step 1: Determine the oxidation state of platinum (Pt)
In the complex \([Pt(Cl)_6]^{2-}\), we know that each chlorine (Cl) has an oxidation state of -1. Since there are 6 chlorine atoms, their total contribution to the charge is \(6 \times (-1) = -6\). The overall charge of the complex is -2.

Let the oxidation state of platinum be \(x\). The equation can be set up as follows:

\[
