An isoelectronic species having larger size than `CI^(-)` is ……..

Explanation

To solve the question regarding an isoelectronic species that has a larger size than Cl⁻, we can follow these steps:

### Step 1: Understand Isoelectronic Species
Isoelectronic species are atoms or ions that have the same number of electrons. For example, Cl⁻ has 18 electrons (17 from Cl and 1 extra from the negative charge).

**Hint:** Remember that isoelectronic species must have the same total number of electrons.

### Step 2: Identify the Electron Configuration of Cl⁻
