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?

Arise 8 run 1 this means go 8 up and 1 across, which is steepest

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
