What do you understand by isoelectronic species? Name a species that will be isoelectronic with each of the following atoms or ions:
`F^(-)`

Explanation

**Step-by-step Solution:**

1. **Definition of Isoelectronic Species:**
Isoelectronic species are atoms, ions, or molecules that have the same number of electrons. This means they have identical electron configurations, even though they may differ in their number of protons and, therefore, their chemical properties.

2. **Determine the Electron Configuration of F⁻:**
The atomic number of fluorine (F) is 9, which means a neutral fluorine atom has 9 electrons. When fluorine gains one electron to form the fluoride ion (F⁻), it now has 10 electrons.
