How can a charged atom (an ion) attract a neural atom

How can a charged atom (an ion) attract a
neutral atom?
1. The charged atom can emit x rays to
induce ionization of the neutral atom.
2. An ion polarizes a nearby neutral atom,
so that the part of the atom nearer to the ion
acquires a charge opposite to the charge of the
ion, and the part of the atom farther from the
ion acquires a charge of the same sign as the
ion.
3. The charged atom can produce secondary
electrons to interact with the neutral atom
and make it positively charged or negatively
charged.
4. The charged atom can hit the neutral
atom and make it positively charged or nega-
tively charged.

9) How can a charged atom (an ion) attract a neutral atom?

2 ..... An ion polarizes a nearby neutral atom, so that the part of the atom nearer to the ion acquires a charge opposite to the charge of the ion, and the part of the atom farther from the ion acquires a charge of the same sign as the ion. The side of the atom closer to the ion is then attracted more strongly to the ion than the farther side is repelled, making for a net attraction. (By Newton's third law, the ion, in turn, is attracted to the atom.)
