Virtually all particles in the air have a positive charge, while negative ions have a negative charge. In which case, negative ions and particles magnetically attract to one another. When there is a high enough concentration of negative ions in the air, they will attract to floating particles in large numbers.
A positive ion is called an optimistic would-be atom and a negative ion is called a pessimistic (and courting disappointment) soon-to-be atomâ¦. No, seriously they are , respectively, cations (positive) and anions (negative) Perhaps confusingly, the positive ion has lost something - an electron (sub-atomic particle carrying a one-unit negative charge) - whilst the negative ion has gained one (compared to the neutral state of the atom, in which the positive and negative charges are balanced).
