An atomic physicist is investigating a sample of gaseous ions. Her analysis shows that an ion had a charge of 17.6 \times 10^{-19}\,\text C \pm 0.2 \times 10^{-19}\,\text C17.6×10 −19 C±0.2×10 −19 C17, point, 6, times, 10, start superscript, minus, 19, end superscript, start text, C, end text, plus minus, 0, point, 2, times, 10, start superscript, minus, 19, end superscript, start text, C, end text. The magnitude of an electron's charge is e=1.60\times 10^{-19}\,\text{C}e=1.60×10 −19 Ce, equals, 1, point, 60, times, 10, start superscript, minus, 19, end superscript, start text, C, end text. Should the physicist be concerned about the validity of the experimental results?
