A `._(92)^(238)U` undergoes alpha decay. What is the resulting daughter nucleus?

Explanation

To determine the resulting daughter nucleus when Uranium-238 undergoes alpha decay, we can follow these steps:

### Step 1: Understand the Process of Alpha Decay
Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle. An alpha particle consists of 2 protons and 2 neutrons, which is essentially a helium nucleus.

### Step 2: Identify the Parent Nucleus
The parent nucleus in this case is Uranium-238, denoted as \( _{92}^{238}U \). Here, the atomic number (Z) is 92, and the mass number (A) is 238.
