The overall atomic weight of neon, 20.2, was the average atomic weight of these 2 isotopes. THE OVERALL ATOMIC WEIGHT OF NEON TWENTY POINT TWO WAS THE AVERAGE ATOMIC WEIGHT OF THESE TWO ISOTOPES
neon ion carrying a single positive charge—an ion that could be written Ne⁺. The neon ions move in the electric field as electrons do, but in the opposite direction since they have an opposite charge. In the combined presence of a magnet and of an electric field, the neon ions move in a curved path. If all the neon ions had the same mass, all would follow the same curve. If some were more massive than others, the more massive ones would curve less. The neon ions ended on a photographic plate, which was darkened at the point of landing. There were two regions of darkening, because there were neon ions of two different masses that curved in two different degrees and ended in two different places. Thomson showed, from the amount of curving, that there was a neon isotope with an atomic weight of 20 and one with an atomic weight of 22—²⁰Ne and ²²Ne. What’s more, from the intensity of darkening, it could be seen that ordinary neon was made up of atoms that were roughly 90% ²⁰Ne and 10% ²²Ne. BE WRITTEN IN E PLUS THE NEEON IONS MOVE IN THE ELECTRIC FIELD AS ELECTRONS DO BUT IN THE OPPOSITE DIRECTION SINCE THEY HAVE AN OPPOSITE CHARGE IN THE COMBINED PRESENCE OF A MAGNET AND OF AN ELECTRIC FIELD THE NEEON IONS MOVE IN A CURVED PATH IF ALL THE NEEAN IONS HAD THE SAME MASS ALL WOULD FOLLOW THE SAME CURVE IF SOME WERE MORE MASSIVE THAN OTHERS THE MORE MASSIVE ONES WOULD CURVE LESS THE NEEON IONS ENDED ON A PHOTOGRAPHIC PLATE WHICH WAS DARKENED AT THE POINT OF LANDING THERE WERE TWO REGIONS OF DARKENING BECAUSE THERE WERE NEON IONS OF TWO DIFFERENT MASSES THAT CURVED IN TWO DIFFERENT DEGREES AND ENDED IN TWO DIFFERENT PLACES THOMPSON SHOWED FROM THE AMOUNT OF CURVING THAT THERE WAS A NEON ISOTOPE WITH AN ATOMIC WEIGHT OF TWENTY AND ONE WITH AN ATOMIC WEIGHT OF TWENTY TWO NEON TWENTY AND NEON TWENTY TWO WHAT'S MORE FROM THE INTENSITY OF DARKENING IT COULD BE SEEN THAT ORDINARY NEON WAS MADE UP OF ATOMS THAT WERE ROUGHLY NINETY PER CENT NEON TWENTY AND TEN PER CENT NEON TWENTY TWO
