41. So if positive ions are excreted, an equal quantity of negative ions have to go along with them. 42. In addition, positive ions slowly drift westward and negative ions drift eastward, giving rise to a ring current. 43. For ionic compounds, the positive ion is almost always listed first and the negative ion is listed second. 44. Electrons in solution can only exist for nanoseconds before connecting with a molecule to form a negative ion . 45. If the voltage is large enough, essentially all electrons ( and any negative ions ) will be repelled. 46. Current scientific studies support his findings, and negative ion therapy may be useful in alleviating depression in some people. 47. Nested ICR cells with double pair of grids were also fabricated to trap both positive and negative ions simultaneously. 48. This presented a large discrimination in kinetic ion acceleration between positive and negative ions trapped simultaneously inside the new cell. 49. "But if I hadn't bought it, I'm sure I'd have regretted it, wondering what the negative ions were like ." 50. A public bath in Osaka, central Japan, offers a tub brimming with negative ions to get blood circulation going strong.
