Step 1
: Identify the electron configuration for the given atoms.

- Neon (Ne): 1s$^2$ 2s$^2$ 2p$^6$ 3s$^2$ 3p$^6$

Step 2
: Determine the subshell from which an electron is removed to form a + 1 cation.

- Neon (Ne$^+$): An electron is removed from the 3s subshell to form a +1 cation: 1s$^2$ 2s$^2$ 2p$^6$ 3s$^1$

Final Answer

- H$^+$: 1s$^1$ - F$^+$: 1s$^1$ 2s$^1$ 2p$^1$ - Fe$^+$: 1s$^1$ 2s$^1$ 2p$^1$ 3s$^1$ 3p$^1$ 3d$^1$ 4s$^1$ - Ne$^+$: 1s$^1$ 2s$^1$ 2p$^1$ 3s$^1$ - H$^-$: 1s$^1$ - F$^-$: 1s$^1$ 2s$^1$ 2p$^1$ - Fe$^-$: 1s$^1$ 2s$^1$ 2p$^1$ 3s$^1$ 3p$^1$ 3d$^1$ 4s$^1$ - Ne$^-$: 1s$^1$ 2s$^1$ 2p$^1$ 3s$^1$
