An atom of an element has two shells with electrons.The valence shell has 2n + 1 electrons where n is the number of electrons in the innershell. This element can form a radical X with hydrogen and two radicals Y and Z with oxygen, Z has more number of oxygen than Y. Identify the element and the radicals. Write the reaction taking place between solutions of two salts, AgZ and XCl. Identify the type of reaction.

Explanation

To solve the problem step by step, follow these instructions:

### Step 1: Identify the Element
We know that the atom has two shells. The inner shell (K shell) can hold a maximum of 2 electrons, and the outer shell (L shell) has \(2n + 1\) electrons, where \(n\) is the number of electrons in the inner shell.

- Since the inner shell has 2 electrons, we have:
\[
n = 2
