1) Anions carry a negative charge (by definition). 2) A negatively charged body would be *attracted* to a positively charged nucleus. The force is only zero while the anion is completely external to the Ni atom. As soon as it is inside the outermost electron shell, it begins to feel an attractive force, that rapidly gets stronger as it burrows deeper, for two reasons, decreasing distance, and less shielding. 3) Any magnetic force would be in *addition* to the electrostatic attraction force. > >* The f/H anion would enter the Ni atom and kick out an electron keeping >it a net neutral body.

The same force (ZPE) which >keeps any electron away from the nucleus also operates against this anion. Negative muons would appear to disagree with you.
