In nuclear reaction `""_1^1Hto""_0^1n+""_Q^Px` find P, Q and hence identify x.

Explanation

To solve the nuclear reaction \( _1^1H \to _0^1n + _Q^Px \), we need to identify the values of \( P \), \( Q \), and the element \( x \).

### Step 1: Analyze the given reaction
The reaction involves a hydrogen nucleus (proton) transforming into a neutron and another particle. We need to conserve both the atomic number (charge) and the mass number.

### Step 2: Write down the known values
- The hydrogen nucleus \( _1^1H \) has:
- Atomic number (Z) = 1
