Which is more unstable of each of the following pairs, and in each case what type of process could the unstable nucleus undergo?
`F^(18)`, `._(10)Ne^(18)`

Explanation

To determine which of the two isotopes, \( F^{18} \) (Fluorine-18) or \( Ne^{18} \) (Neon-18), is more unstable and what type of decay process the unstable nucleus could undergo, we will follow these steps:

### Step 1: Identify the atomic numbers and mass numbers
- For \( F^{18} \):
- Atomic number (Z) = 9 (Fluorine)
- Mass number (A) = 18
- For \( Ne^{18} \):
- Atomic number (Z) = 10 (Neon)
